Year 13 Further Maths homework to Wednesday 1 November

Click here to download pdf: https://mathsmartinthomas.files.wordpress.com/2017/10/preparatory-practice-y13.pdf

This worksheet is designed to give you one or two questions covering every important idea we’ve covered this term, mostly with a bit of explanation or revision notes before the question(s).

Every question is taken from the textbook so, if stuck, you can check with Solution Bank. (You can of course email me, too).

The worksheet will prepare you for the test, which you’re also asked to do outside class time, between now and 1 November. The test will cover exactly the same ground.

Year 12 Further Maths homework to Wednesday 1 November

Do ten questions from this question sheet:

Edexcel complex numbers assessment question sheet: https://mathsmartinthomas.files.wordpress.com/2014/09/171017edexcelcomplexnumbersassessment.pdf

Some of the questions you’ve done for your 18 October homework, and some you’ve done for your 20 October test. Please select some new ones.

Q.21 looks like there’s a typo in it, and they mean to describe the equation as:

x4 + ax3 + bx2 + cx + d = 0

I think Q.17 may have a typo in it, too. The square root involves a complicated surd. With the calculator method you can only get an approximate square root: you can’t see that the decimal you get on the calculator is in the way you can see that 1.414213562 is √2. On the other hand, maybe they only want an approximate answer in decimals: they don’t say: give the answer as an exact surd. I’d skip Q.17.

Other than that: choose questions nearer the end of the question sheet if you’re confident and want to push yourself, choose questions nearer the start if you’re feeling less confident.

I’ll post worked answers for all the questions here soon.


Year 13 Further Maths homework to Wednesday 18 October

Part C: Calculate these values

sin 0

cos 90



Year 13 Further Maths homework to Wednesday 20 September

Part A: to come, in individual notes to each of you.

Part B: finish pages 27 and 30 of the Maclaurin workbook.

Page 27

Exercise 6E, page 122. Q.2. The variable y satisfies
(1+x^2)\frac{d^2y}{dx^2} + x \frac{dy}{dx} = 0
and at x=0
y=0, \frac{dy}{dx} =1
Find a series expansion for y in ascending powers of x up to and including the term in x3

Q3. Given that y satisfies the differential equation
\frac {dy}{dx} + y - e^x = 0
and that at x=0, y=2, find a series solution for y in ascending powers of x up to and including the term in x3

Page 30

(Worked example 8 from textbook, p.113): Given that terms in xn may be neglected for n>4, show that:
\mathrm{e}^{\sin x} \approx 1 + x + \frac{x^2}{2} - \frac{x^4}{8}

[Note: this is done in the book in a different way from how we did in class, but either way is fine]

Find the first few terms of a Maclaurin series for y = (1-x)^{-2}

Q.8 from textbook, p.114: Expand
\frac{\sin x}{(1-x)^2}
in ascending powers of x as far as the term in x3 by considering the product of the expansions of sin x and (1−x)-2

[Note: this means: write out the Maclaurin series for

sin x

and for

(1-x)−2

up to the terms in x3, and then do the multiplication of the two series as if they were polynomials.
\sin x = x - \frac{1}{6}x^3 + \ldots
(1-x)^{-2} = 1 + 2x + 3x^2 + 4x^3 + \ldots
When you multiply, the constant term is zero (because zero constant term in the series for sin x), and the coefficient of the x3 term is:

3 (from x term in first series times x2 term in second) − \frac{1}{6} (from x3 term in first series times constant term in second)

You need to find the coefficients of the x and x2 terms.]

[Further note: the first answer on page 26 of your Maclaurin workbook is wrong, sorry, because I copied it from the textbook, but I also slightly changed the question when copying from the textbook. The answer we got in class is right. I’ve changed the pdf of the workbook on this website].

Part C: Differentiate these using the chain rule and the product rule

(1−x)−3
(1−ex)−1
x3ex


Year 12 Further Maths homework to Wednesday 13 September

Part B: finish off pages 5, 6, and 13 of your complex numbers workbook

Part C: do these surd calculations

\frac{5+\sqrt{3}}{3-\sqrt{3}}

\frac{1+\sqrt{5}}{1-\sqrt{5}}

\frac{1+\sqrt{7}}{1-\sqrt{7}}

\frac{1}{1-\sqrt{7}}


Year 13 Further Maths homework to Wednesday 13 September

Part B: finish off pages 22, 23, 24, 29 of the Maclaurin workbook, as below

Your basic formulae for all this are

a_0 = y \lvert_{x=0}

a_n = \frac{1}{n!} \cdot \frac{d^ny}{dx^n} \lvert_{x=0}


Calculate the Maclaurin series up to the x5 term for

y = \cos x


y = \cos x is also the solution to the differential equation

\frac{d^2y}{dx^2} = - y with y=1 and \frac{dy}{dx} = 0 when x=0. Get the same Maclaurin series from the differential equation.


Calculate the Maclaurin series for

y = \ln (1+x)


\mathrm{e}^x \approx 1 + x + \frac{x^2}{2!} + \frac{x^3}{3!} + \frac{x^4}{4!} + \frac{x^5}{5!}

\cos x \approx 1 - \frac{x^2}{2!} + \frac{x^4}{4!}

\sin x \approx x - \frac{x^3}{3!} + \frac{x^5}{5!}

Use these approximations to calculate
\mathrm{e}, \sin \frac {\pi}{6}, \cos \frac {\pi}{6}
and compare your answers with what you get from your calculator.


(Q.4 from textbook, p.111): Using the series expansions for

\mathrm{e}^x

and

\ln (1+x)

respectively, find, correct to 3 decimal places, the value of:

(a) \mathrm{e}

(b) \ln (\frac{6}{5})


(Q.5 from textbook, p.111): Use Maclaurin’s expansion and differentiation to expand, in ascending powers of x up to and including the term in x4

(a) \mathrm{e}^{3x}

(b) \ln (1+2x)

(c) \sin^2 {x}

[Note: \sin^2 {x} means (\sin {x})^2 ]

Part C

Use the product rule and the chain rule to differentiate:

y = sin x . cos x

y = x . sin x

y = x2 . cos x

y = exp (x2)

Writing maths and conics: write out one of the solutions to Ex.2G Q.4 part (b) (assuming part (a)) as clearly and concisely as you can. Here are my writings-out of the three solutions: see if you can improve on them.

Three solutions

Write out, as clearly and concisely as you can, two proofs of the fact that if A and B are foci of an ellipse (S′ and S in the diagram below)

and P is a point on an ellipse, than PA+PB=2a

One, by using the fact that every point P on the ellipse has

distance from the focus = e × distance from the directrix

as shown in Example 16, p.37 in the textbook.

Two, by putting

P = (a cos θ, b sin θ), A = (-ae, 0), B = (ae, 0), b2 = a2 (1 − e2)

and doing the algebra.

Homework for 18 January

Please mark your own work before handing it in.

Year 12 Further Maths

1. Consolidation of the work we did today on different ways of picturing complex numbers

These names can be divided into two groups: some describe different ways of looking at one particular quantity, and some of them different ways of looking at a different quantity.

List the two groups

modulus
argument
magnitude
direction
angle
enlargement
rotation
square root of determinant

2. Examples to get used to the ideas we learned today
Q.24 p.66
Q.26 p.66
Ex.4E Q.3 (you’ve done this before, but you may now find it easier)
Ex.1I Q.9 (you need to switch into geometry here: it’s a question Y12 students usually find difficult)

3. Consolidation on transforming triangles with matrices

Ex.4I Q.1 and 2

(You can use my worked answer to question 7(ii) from the mock to help you. All the questions of this sort are pretty much the same once you are used to them.)

Your choice of homework: a past paper from the past-papers booklet (skipping the Newton-Raphson, parabolas, and hyperbolas questions), or whatever you prefer to practise to get ready for the mocks. Whatever you do, please mark it yourself and bring it to me to check on Wednesday.

Year 13 Further Maths

Polar coordinates: finish off
Ex.7C Q.1-2
Ex.7D Q.1-9
Ex.7E Q.2

In addition, each of you has work yet to complete from the holiday assignment:

Practice Paper A, and mark scheme

Practice Paper B, and mark scheme

June 2014 (R) paper and mark scheme.

See my comments on the 4 January homework for what each of you, individually, should do.


Homework for 4 January

Year 13 Further Maths

First re-do the test you did on 15 December.

Check your work against the mark scheme and my worked answers, spot where you went wrong, then do this same paper again straight away at the start of the holidays, and mark it yourself.

(Then we’ll do the exact same paper again at the start of the January term, before going on to polar coordinates).

Paper at:

FP2 paper done on 15/12/16

Worked answers at:

FP2 June 2016 worked answers

Mark scheme at:

FP2 June 2016 mark scheme

Over the rest of the holidays, please do these three papers from your FP2 past-papers pack:

Practice Paper A

Practice Paper B

June 2014 (R)

These are also available online at:

Practice Paper A, and mark scheme

Practice Paper B, and mark scheme

June 2014 (R) paper and mark scheme.

Give yourself 90 minutes for each one. Skip the polar coordinates questions, since we haven’t covered that yet.

Then give yourself another 90 minutes to:

  • do any problems you ran out of time on
  • check the answers against the mark scheme, and mark your work. Calculate your percentage and write in into your FP2 past-papers pack.
  • using the mark scheme, work out how to do any problems you got stuck on, or made mistakes in
  • email me at mthomas@cityacademy.co.uk for help if and when you’re still baffled

Year 12 Further Maths

Please do these three made-up “practice papers”. Give yourself 90 minutes for each one.

Then give yourself another 90 minutes to:

  • do any problems you ran out of time on
  • check the answers against the back of the book, and mark your work. Give yourself 4 for each completely correct answer, 2 for half-correct, 1 for quarter-correct, etc., so you get a total mark of out 40
  • using Solution Bank, work out how to do any problems you got stuck on, or made mistakes in
  • email me at mthomas@cityacademy.co.uk for help if and when you’re still baffled

The second 90 minutes is as important as the first 90 minutes. Of course, if you get all the questions completely right straight off, then the “second 90 minutes” may be less than 90 minutes.

That makes 9 hours’ FP1 work altogether, out of the 408 hours of the Xmas holidays. Please hand in the work to me in the first week of the January term.

Homework for Tue-Wed 4-5 October

Year 12 Further Maths: Finish the proofs by induction with series up to Q.1,2,3 on p.16 in the workbook. (Q.4 and 5 on p.16 you’ve done already, so you can skip them). If you have time, go on to the proofs by induction with divisibility on page 17 and the following pages. If you have mislaid the workbook or not taken it home, you can download it at https://mathsmartinthomas.files.wordpress.com/2016/09/workbook-induction3.pdf

Exceptions: Vinh, Peter, Tegan, Bolaji: please do as much as you can of the divisibility examples in the proof-by-induction workbook.

Daniel, David: please do Q.5, 6, 8 of Ex.6A from the textbook.

Michelle, Abdal: just do as much as you can from the workbook, starting from where Onesimus and Rashi and Ashley helped you to get up to on Friday.

Year 13 Further Maths: Using De Moivre. Finish off Q.2, 3, 5, 6, 7 of Ex.3D (p.36); then, if you can (the questions involve a lot of working, but you’ll get quicker with practice) Q.1, Q.2, Q.3 a, b, c, Q.4, of Ex.3I (p.61).


Homework for Wed 28 September

Year 12 Further Maths: Your homework is to finish off the examples we worked on in class about proof with sequences:

1. Exam questions on page 9 of the workbook

2. Questions 1 to 4 from p.132-3 of the textbook (Exercise 6C)

3. Q.6 from p.132-3 of the textbook (Exercise 6C)

You don’t have to do Q.7 and 8 of Exercise 6C

As always, email me if you come across problems or difficulties. How do you mark your own work? Tick each proof if you’re happy that it is a convincing argument to prove the answer correct; mark it with a question-mark if you’re not sure.

Year 13 Further Maths: From your “Further complex numbers: exercises and answers” booklet, do:

1. “Exercise on exp and ln functions”, ninth page in the booklet (with “41” on bottom right corner of photocopy)

2. “Exercise 3A”, eleventh page in the booklet (with “23” on bottom right corner of photocopy)

3. More Möbius questions if I’ve asked for them in my comments on your last homework

Homework for Wednesday 21 September

Please make sure it’s in my blue tray in 2B7 by close of school on Tuesday, or Wednesday before tutor group at latest. Please mark your own work before handing it in.

Year 13 Further Maths: do three more questions (or more if you think you need more practice to get good) by the geometric method from the booklet of FP2 past paper questions

FP2 past-paper questions (Möbius)

Use the worked answers to check your work.

You may choose to skip Q.6 and Q.9 at this point. Q. 6 (“The point P represents a complex number z on an Argand diagram, where |z+1|=|2z-1|…”) is very much designed to be done by the algebraic method, and the geometric method is not specially faster for that one. Q.9 (“The transformation T from the z-plane, where x=x+iy…”) is written to demand you do it by the algebraic method (though you can check it by the geometric method, and it’s much quicker).

Homework to be done for the start of term, 8 September 2016

Year 13 FP2 Further Maths:
1. Re-read your “Möbius transformations” colour-printed booklet. (Download a revised edition here if you don’t have your printed copy to hand).
2. Read the proofs at https://mathsmartinthomas.wordpress.com/2015/08/18/images-of-loci-of-complex-numbers/
3. Re-do Activity 8 – Example 36, and questions 13 and 15, on the 7th page of the booklet – by the geometric method. (You’ve already done them by the algebraic method).



Homework for 7 July 2016

Year 13 (formerly Year 12) Further Maths: From your “Transformations of the complex plane” colour-printed booklet (click here to get it online):

do the exercises on the 7th page by the algebraic method. (We will study how to do them by the geometric method next week).

Heading on your work (you should have left your book with me for marking, and so you’re doing the homework on loose-leaf paper): Algebraic method: examples.

That is “Example 36”
“Q.13”
“Q.15”

hwk7july

All these are examples where an ordinary circle (not a line) is transformed into an ordinary circle (not a line).

Click here for the worked answer from the book for example 36. The answer for Q.13 (from Ex.3H in book) is circle with centre (9/2, −3/8) and radius 15/8; the answer for Q.15 (from Ex.3I in the book) is circle with centre (−2,−4) and radius 2√5.

Steps in the algebraic method:

# Change subject of equation so that it’s “the wrong way round”, i.e. if you have a known locus in the z-plane and want to find the w-locus, change the subject of the equation to “z=….”

# Write w=u+iv (so u=Re(w), v=Im(w)) and put the equation in terms of u and v

# Use what you know about z (it might be |z|=2 if the z-locus is a circle, centre the origin, radius 2; or Re(z)=Im(z) if the z-locus is the line y=x; or Re(z)=Im(z)≥0 if the z-locus is the half-line arg(z)=π/4) to get an equation for u and v

# If that equation has expressions like |(u−1)+i(v+1)| in it, square both sides to get an equation without |…| signs in terms of u and v

# Expand, collect terms, simplify

# Fiddle with the equation for u and v to get it in a standard circle or line form

Click here for some worked examples.


Homework for 28 June

Year 13 (formerly Year 12) Further Maths: From your “Further Complex Numbers” exercises booklet (click here to get it online), do as many as you can of Exercise 3H Q.1, 3, 5, 6. Heading in your books: Transformations of the complex plane.

Work through these notes, and you’ll find it all not so difficult.

Ex.3H Q.1 (a). “The circle |z|=1” means that you draw in the z-plane a circle of all the complex numbers z which have modulus (=”size”=distance from the origin) equal to 1. That is, a circle, centre the origin, radius 1.
Then the transformation w=z+4+3i means that the image in the w-plane is a similar circle, shifted 4 units to the right, 3 units up.

(b) “The half-line arg(z)= π/2” means that you draw in the z-plane the line which is all the complex numbers at an anticlockwise angle of π/2(=90 degrees) to the positive real axis. That’s just the positive imaginary axis. It’s called a half-line… well, because it’s half a line.
In the w-plane you draw a similar half-line, but shifted 4 units to the right, 3 units up.

(c) No mystery about how to draw the line y=x. It’s a full line 45 degrees anticlockwise from the positive real axis. In the w-plane you draw a similar half-line, but shifted 4 units to the right, 3 units up.

Never mind about Q.2. You can skip that.

Questions 3 and 5 are just the same sort of thing as question 1.

Question 5 looks a bit scarier, but it isn’t really. “The circle |z−1|=3” is just a circle in the complex plane with centre 1 and radius 3. “The half-line arg(z−1+i)=π/4” is a half line starting at 1−i and going up and to the right at an angle of π/4 (45 degrees) anticlockwise from the positive real axis.

Question 6 is the only one which introduces something more complicated than enlargement and translation.

w=1/z. You work that out in algebra by changing the subject of the equation.

z=1/w

Then when |z|=2, |1/w|=2, so 1/|w|=2, so |w|=½. So in the w-plane you draw a circle with centre the origin and radius ½.

When arg(z)=π/4, Re(z)=Im(z) and both are positive. So Re(1/w)=Im(1/w).

Call the real and imaginary parts of w, u and v, so w=u+iv

Then 1/w=1/(u+iv)=(u−iv)/(u2+v2)

So Re(1/w)=Im(1/w) means u=−v. And if Re(1/w) and Im(1/w) are both positive, u is positive.

In the w-plane, the up-and-down axis (what you would usually call the “y-axis”) is the v-axis, and the across axis (what you would usually call the “x-axis”) is the u-axis.

So, draw the line u=−v, or rather, the bit of it for which u is positive.

    Homework for Tuesday 26 April 2016

    The first bit of homework, for everyone, is to work through the comments I’ve written on your previous homework, and make another effort to complete questions you had trouble with (or failed to attempt) first time round. Then:

    Year 13 Maths

    Do six questions of your choice from the trig past-paper questions booklet.

    https://mathsmartinthomas.files.wordpress.com/2015/12/c3_trigonometry1.pdf

    If you’re confident about that, do:

    Ex.7E Q.8, 9, 10c, 11a, from the C3 book (p.127-8). These are on the “factor formulae”, which are in the formula book and in the textbook. They rarely come up in the exam, but, who knows, this year might be the year.

    Or if you feel super-confident about all of trig, do another C3 or C4 past paper of your choice.

    Do these short exercises to consolidate your understanding of what to do when you get an induction question about divisibility and in part (a) it asks you find something like f(k+1)−f(k)

    Then do six further questions from the Review Exercises in the textbook on parabolas and hyperbolas.

    Year 13 Further Maths

    1. Do a check-the-answers on the FP3 mock paper and the FP2 2014 paper at:

    https://mathsmartinthomas.files.wordpress.com/2015/05/fp3_checks.pdf

    showing your reasoning in each check.

    2. Do an FP2 or FP3 past paper of your choice. If you find that too much, make sure that at least you do the check-the-answers.

    FP3: Matrices.

    1. Watch the first four videos at https://mathsmartinthomas.wordpress.com/2015/12/23/inverting-matrices-using-the-casio-991es-and-using-rref-video-clip/.
    2. Ex.6A, Q.2a, 4a

    2. Do questions 2 and 3 from the booklet of past-paper questions on parabolas and hyperbolas

    fp1-parameters-pastq

    Or (if you prefer, since you have answers with the questions) two questions from this question sheet on parabolas and hyperbolas:

    Question sheet with worked answers

    C4: Integration from standard results, plus follow-up

    1. Do the follow-up I asked you, individually, to do from your holiday homework. If you’re at all unclear about what that is, just do another C3 past paper.
    2. Ex 6B Q.3a, e, i, and Q4a


    Homework for 5 January 2016
    Note for everyone: how to do past papers
    Give yourself 90 minutes for each paper, in as near exam conditions as you can manage. Have a formula book to hand – it’s available on the web.
    After you’ve done 90 minutes, check your work against the mark scheme. Mark it. Give yourself a realistic estimate of how well you’re doing. Learn from your mistakes: puzzle out how to do questions you got wrong or didn’t find time to get to.
    After you have marked and corrected your paper, please scan it and email it to me.

    FP1:
    Almost everyone did better than in the mid-term exam, and some people much better.
    We aim for everyone to get at least a C in the mock exam second week back, and at least six of you to get a A.
    On the evidence of the test you did on 11 December, that’s possible, if you can all make an effort to fix weak areas in your learning and to increase your confidence. But only with that effort.
    1. I have written up, and posted on this site, detailed comments on the test you did on 11 December; and send each of you an individual email about your individual paper.
    The test paper itself is available on this site.
    Please work through the test paper, convincing yourself that you can do all the questions, identifying the mistakes you made in the actual test, learning from them.
    2. On Nii’s suggestion, I’m collecting and making some video clips about bits of FP1, especially the bits we’ve done differently from the textbook.
    They’re at https://mathsmartinthomas.wordpress.com/category/video-clips/
    Watch them with a pen and paper to hand, working through the examples discussed in the videos, pausing or rewinding from time to time to make sure you’re confident.
    3. Please do three more FP1 past papers. You have a booklet of past papers. If you’ve mislaid the booklet, it’s online (with mark schemes) on this website. Check out some trickier FP1 questions here: if you feel confident that you’ve covered similar questions in the FP1 past papers you’ve done, fine; if not, please work through those trickier questions (solutions are provided).

    FP2
    1. Please work through the test paper you did on 11 December. Purpose: to convince yourself that you can do all the questions, identify the mistakes you made in the actual test, and learn from them.
    I’ve posted the test paper and the mark scheme on this website.
    2. Please do at least three more FP2 past papers.
    You can find past papers on this website. Do each paper by giving yourself 90 minutes for it, in as near exam conditions as you can manage. Have a formula book to hand – it’s on the web. You can find collections of past-paper questions by topic on this website.
    3. Please work through the rest of the chapter on Maclaurin and Taylor.
    The hard thing to understand here is the concept of expressing all functions, all well-behaved functions anyway, as infinite series. We’ve covered that and you need to consolidate it by working through the other bits in the book.
    Use the exercises in the book, but do questions only from the beginning of each exercise and from the Review Exercises. The book contains some questions on Maclaurin and Taylor which are significantly more complicated than anything you’ll meet in the exam.
    Beyond a certain level, it’s best to practise this topic by directly doing actual past-paper questions: there’s a selection on this site.
    Usually in FP2 there is only a half-question or one-third-question on Maclaurin and Taylor, and that a pretty simple one.

    C3
    1. I will write up for each of you an individual email about your individual 11 December test paper. Please read that email.
    Almost everyone did worse than I expected in that test paper. But no-one did so badly as to look hopeless. The odd thing is, generally you got the difficult things right and the easy things wrong.
    That’s the sort of problem that is fixed by practice. With enough practice, I think everyone can get at least a C, and the majority can get an A. But only with enough practice…
    2. Please do at least three more C3 past papers.
    You can find past papers at:
    http://www.physicsandmathstutor.com/a-level-maths-papers/c3-edexcel/


    Homework for 8 December 2015

    Everyone: please first look at the marking of your last homework. Make sure you’ve written a “student response” (in red). If you’re asked to do something extra, do that first.

    And, with every week’s homework, please mark it yourself, before you hand it in.

    FP2

    FP2 June 2013 withdrawn paper (except Q.1(c) and Q.3(c), which you won’t yet be able to do because you haven’t yet studied Maclaurin and Taylor series). Click here for a mark scheme. Please give yourself 90 minutes to do the paper, and mark your work against the mark scheme.

    FP1: FP1 June 2014, from this collection, which also includes a mark scheme for the paper. Skip questions 6 and 8, which you won’t be able to do because you’ve haven’t yet studied parametrics. Please mark your work against the mark scheme.

    C3: One more C3 past paper. That is probably June 2007 for most of you, but anyway, the next past paper you haven’t done. Please mark your work against the mark scheme. Click here to get the past papers and mark schemes online.



    Homework for 1 December 2015

    C3

    Heading for this homework: Past papers

    Mark the June 2005 past paper you did in class. Give yourself exactly 90 minutes to do the January 2006, and mark that. Give me both marked papers on Tuesday 1 December, please.

    FP2

    Heading for this homework: Second order differential equations

    Ex. 5F Q.1,2; Ex.5G Q.1, 3, 6; Review Exercises p.147 Q.17,18

    FP1

    Heading for this homework: Matrices

    Complete (you’ll have done some in class) the following:

    matrix addition – Ex.4A Q.2 and Ex.4B Q.1

    matrix multiplication Ex.4C Q.2(b), 7, 8

    seeing what matrices represent geometrically Ex.4D Q.5 and Ex.4E Q.1-3

    determinants Ex.4I Q.4



    Homework for 24 November 2015

    C3

    Heading for this homework: Differentiation

    Three more questions from differentiation past-paper questions.

    FP2

    Heading for this homework: Second order differential equations

    Ex.5C, Q.1, 3, 5, 7, 9

    FP1

    Heading for this homework: Mopping up complex numbers

    Do Ex.1I, p.30, Q.5, 7, 8, 9. (Also Ex.1G Q.1, 2, 9 if you didn’t finish them in class).

    ex1i-q5789

    These are about as difficult as you’ll get for FP1 complex numbers questions. Year 12 students generally find Q.9 difficult. But all it needs is a little thinking. You can also email me for help when you get stuck.

    ===



    Homework for 17 November 2015

    FP2

    Heading for homework: First-order differential equations

    Ex.4C Q.8 and 9 and Ex.4D Q.1-3

    Because our lesson on Thursday was cut short, please read the relevant pages in the textbook carefully and work through Example 10 in the book before starting your homework.

    e∫Pdx can also be written as exp [∫Pdx]. Quite often you can guess the integrating factor without having to go through the exp [∫Pdx] formula.

    C3

    Heading for homework: Past-paper questions on trigonometry

    Do three more questions from the past-paper booklet I gave you: C3 past-paper questions on trigonometry. You can check your answers against the mark schemes.

    FP1

    Heading for homework: Solving cubics

    Find all three roots of the cubics in questions 1 to 8. (We went through Q.1 to 3 in class. I’ve worked Q.1 below as an example).

    Facts to use:

    If z = x+iy = r cis θ, the conjugate of z is z* = x–iy = r cis (–θ)

    • [1] If z is a root of a cubic or a quartic (an equation with z4), then z* is also a root
    • [2] Sum of roots = − coefficient of second highest power in the equation (coefficient of z2 if it’s a cubic, coefficient of z3 if it’s a quartic)
    • [3] Product of roots = − constant term in the equation if it’s a cubic
      Product of roots = constant term in the equation if it’s a quartic

    Using these facts (actually, just using the first two):

    1. If 1+i is a root of z3−5z2+8z−6=0, find the other two roots

    By fact [1], 1−i is also a root

    By fact [2], the sum of the roots is 5 (because the coefficient of z2 is −5)

    So, if the third root is a, a+1+i+1−i=5. Therefore a=3.

    The three roots are 1+i, 1−i, and 3.

    2. If i is a root of z3−2z2+z−2=0, find the other two roots

    3. If 1+i is a root of z3−2z+4=0, find the other two roots

    4. If 2 cis (2π/3) is a root of z3−8=0, find the other two roots

    5. If 1+2i is a root of z3−3z2+7z−5=0, find the other two roots

    6. If 3+2i is a root of z3−6z2+13z=0, find the other two roots

    7. If 3−2i is a root of z3−9z2+31z−39=0, find the other two roots

    8. If 3−2i is a root of z3−10z2+37z−52=0, find the other two roots

    9. If 3 cis (2π/3) is a root of z3−27=0, find the other two roots

    You can check your answers by clicking here.

    If you get stuck, email me at mthomas@cityacademy.co.uk or ask a Sherpa. Don’t read the textbook. It won’t help. For more on this see the “don’t do as the book says” notes.



    Homework for 10 Nov 2015

    FP2

    Heading for homework: First-order differential equations

    Ex.4B Q.1-6

    C3

    Heading for homework: Past-paper questions on trigonometry

    Do three more questions from the past-paper booklet I gave you: C3 past-paper questions on trigonometry. You can check your answers against the mark schemes.

    FP1

    Heading for homework: Adding, multiplying, dividing, and converting complex numbers

    Finish off these sections of Ex.1a, 1b, 1c, 1e

    1e, Q.1-8: convert from (x+iy) rectangular form into (r,θ) polar form, using Pol on your calculator. “Modulus” is just the “r” of the complex number written in polar form, and “argument” is just the “θ” of the number written in polar form.

    ex1e

    1a, Q.1-10: add, in x+iy form

    ex1a

    1b, Q.1-10: multiply, in x+iy form (it’s like multiplying in algebra, as if i were a variable, except that you then simplify further by replacing i2 by −1)

    ex1b

    1c, Q.3-10, divide, in x+iy form (it’s like dividing with surds. You multiply both top and bottom of the division sum by the conjugate of the bottom number)

    ex1c

    Everyone: please first look at the marking of your last homework. Make sure you’ve written a “student response” (in red). If you’re asked to do something extra, do that first.

    And, with every week’s homework, please mark it yourself, against the back of the book (if you can), before you hand it in.

    FP1: series

    Ex.5E Q.1 and 2
    Ex.5F Q.5 and 6

    C3: trigonometry

    Ex.7A Q.1, 2, 3, and 4 (a), (c), and (d) only

    FP2: mopping up

    Do all of the following questions that you haven’t already done for revision.

    Polar coordinates: p.153-4 Q.62
    Inequalities: p.9 Q.5, Q.7
    Series: p.16 Q.7
    Complex numbers: p.68 Q.30, Q.32, Q.33



    Homework for Tuesday 13 October 2015

    Everyone: please first look at the marking of your last homework. Make sure you’ve written a “student response” (in red). If you’re asked to do something extra, do that first.

    And, with every week’s homework, please mark it yourself, against the back of the book (if you can), before you hand it in.

    This week’s homework is all geared to revision for the tests on 15 and 16 October. If you get stuck, take advantage of the catch-up sessions: Tuesday P1, Thursday P1, or Friday P1, or before tutor group on Tuesday, Thursday, or Friday. Just come to the maths office.

    FP1: revision for test on 16 October

    It’s a lot of homework this week!

    First, do p.40 Q.1 and Q.6 (a) and (b) [not (c)] to make sure you’re good on interval bisection and linear interpolation.

    p40ex

    Second, do this sheet on basic algebra facts you use a lot in induction proofs (and with series): click here for worksheet.

    Third, do a few induction proofs, if necessary by looking at standard examples and copying step-by-step, so that you can manage them at least on a “getting used to it” basis, if not yet quite “understanding”.

    Use this model to write proofs that:

    • if f(n)=42n−1+52n−1, then for all n, 9 | f(n); and
    • if f(n)=52n−1+62n−1, then for all n, 11 | f(n).

    Even if you do it by mechanically copying out and replacing “3” in the model by “4”, and “4” in the model by “5”, etc., it should help you get sufficiently used to divisibility proofs to manage in the test on Friday 16 October.

    9 | f(n) is short for: 9 divides exactly into f(n)

    Use this model induction proof with sequences to do Q.44 on p.141.

    Use this model proof with series to do Q.40 on p.141.

    p141

    If you get stuck, email me and say where you’ve got stuck. You must be able at least to start all these induction proofs, if only just by copying the model proof.

    C3: a bit of trigonometry and revision for test. Ex.6F Q.2. Also make sure you’ve finished Ex.6D Q.1-2 and Ex.6E Q.1 at least. Apart from that, choose your own homework to prepare you for the test on Friday 16 October. The test is on chapters 1, 2, 3, 4, and 8 (not chapter 5, and not the trigonometry we’ve done in chapters 6 and 7). I can tell you that the test doesn’t include anything super-complicated on differentiation, so if you’re confident with Ex.6A you should be all right for the test. Part of your homework is also to name which topics you want to have time in our revision lesson on Thursday 15th.

    FP2: revision for test on Thursday 15 October. Choose your own homework. The test will cover inequalities (ch.1), series (ch.2), De Moivre (ch.3), and polar coordinates. Best choose a few examples from each area and identify where you need to do more work. Email me if you get stuck. Please make sure to hand in your work on Tuesday, so that I can get an idea of what you’re doing with revision, and where you’ve having difficulty.

    We will have 35-40 minutes revision time on Thursday before the test.


    Homework for Tuesday 6 October 2015

    FP1: proof by induction: “Scaffolded” induction proofs with series and “scaffolded” induction proofs with divisibility.

    C3 trigonometry: Ex.6C Q.1-4


    Homework for Tuesday 29 September 2015

    FP1: proof by induction: Do at least six questions from Ex.6A (induction with series)- from the sheet with Ex.6A and 6B (induction). (Don’t do any Ex.6B questions for now). And (if you’ve not finished it already) finish the sheet of re-run past exam questions on induction with sequences. If you finish those with time to spare, do as many as you can of the sheet of past-paper questions on induction with series

    FP2 polar coordinates: Review questions (p.153) nos. 59, 60, 61, 62

    C3 numerical methods: Ex.4C Q.1, 2, 3, 4


    Homework for Tuesday 22 September 2015

    Everyone: please first look at the marking of your last homework. Make sure you’ve written a “student response” (in red). If you’re asked to do something extra, do that first.

    And, with every week’s homework, please mark it yourself, against the back of the book (if you can), before you hand it in.

    Then:

    FP1: proof by induction: Finish the collection of past exam questions on mathematical induction with sequences: Past exam questions on induction with sequences and (if you haven’t finished it yet) the sheet of “extra” induction problems with sequences: Extra induction problems with sequences

    FP2 polar coordinates: Ex.7D Q. 3, 4, 6, 7

    C3 Exponentials and logs: Ex.3C Q.1(a) and (f) only, Q.2(a) and (f) only, Q.3, Q.4.

    FP1: proof by induction Read the booklet on “Mathematical Induction and the Lurgy”.
    Write another example, beside diseases, forest fires, collapsing buildings, and dominoes, of “mathematical induction” in everyday life.

    Do proofs of claims 1 and 2 in that booklet (page 7). You don’t have to attempt Claim 3, or the three examples on page 6.

    Please don’t start reading the textbook, or doing examples from it.

    FP2: polar coordinates Ex.7C, questions 1 to 6, part (c) only of each question. You can use http://www.webmath.com/polar.html to help. Make sure you set the range big enough.


    Homework for Tuesday 8 September 2015

    C3: Algebraic fractions Exercise 1E, Q.1 (a) and (d), Q.2 (a) and (d), Q.3-6.

    FP1: proof Write proofs of two claims chosen from A3 to A5,
    B1, B2, or B4 to B8, in the booklet
    Lesson_and_homework_on_proof; and read the whole booklet through. You can check your answers at https://mathsmartinthomas.files.wordpress.com/2014/08/answers_for_booklet_on_proof.pdf.

    FP2: polar coordinates With diagrams, show what happens to the graph in polar coordinates:

    r = p + cos θ

    as p moves from p=0 to p=2.

    You can use http://www.webmath.com/polar.html to help, especially if you missed the lesson on Thursday 3 September.

    Sketch the graphs of

    r = sin 2θ

    r = sin 5θ

    r = cos 2θ

    θ = π/4

    θ = π/2

    You can use http://www.webmath.com/polar.html to help.

    You can check your answers against the textbook. Remember that the textbook misses out the parts of these graphs where r is negative, so your answer may be right but a bit different from the textbook.


    Homework for Tuesday 14 July

    Lou-Lou and Debora: do as much as you can of Ex.1C (on inequalities) in the FP2 book.

    Everyone else: do these six problems from the website “I want to study engineering”. Write your working in your book as well as your answer!

    http://i-want-to-study-engineering.org/q/children/
    http://i-want-to-study-engineering.org/q/mental_arithmetic/
    http://i-want-to-study-engineering.org/q/graph_sketching3/ (this looks hard, but is the easiest of the graph-sketching questions)
    http://i-want-to-study-engineering.org/q/graph_sketching1/
    http://i-want-to-study-engineering.org/q/graph_sketching2/ (can be done more easily than suggested method on website)
    http://i-want-to-study-engineering.org/q/cubic_equation/ (harder)


    Homework for Tuesday 7 July

    Do these six problems from the website “I want to study engineering”.

    If you get stuck, the website offers help and then a full solution. So you must be able to get the answers one way or another. Obviously, first try to do the problems without using the website help. Please mark your work before you hand it in, giving yourself extra credit if you got a solution without using the website help.

    http://i-want-to-study-engineering.org/q/cards_and_logic/
    http://i-want-to-study-engineering.org/q/arcs_inside_a_square/
    (this last one is harder but doesn’t demand any knowledge you don’t have)


    Homework for Wednesday 1 July

    Please put your homework in my blue tray in the maths office by end of school on Wednesday 1 July.

    Do these six problems from the website “I want to study engineering”.

    Don’t use the “problem generator” on that website, because that may give you a problem that you need year 13 knowledge for. You can do all these six problems with year 12 knowledge and some thinking.

    If you get stuck, the website offers help and then a full solution. So you must be able to get the answers one way or another. Obviously, first try to do the problems without using the website help. Please mark your work before you hand it in, giving yourself extra credit if you got a solution without using the website help.

    From Sharif, Mugisha, Hamse, Juan, Dion, and Joan I also want to see what you’ve done on the MAT symmetry problems and the MAT simple special cases problems. Congratulations to Lou-Lou on her work on the symmetry problems.

    Homework week 5 term 2, due Tuesday 10 February; and work for Friday 6 February, when you’re not in school

    M2: Work for Friday: Do the FP1 practice exam paper on p.142-4 of the FP1 book. Check your answers against the back of the book

    Homework: work, energy, and power. Ex. 3D (p.80) Q. 3, 4, 7, 10, 14

    Remember the work-energy principle *not* the way it is stated in the book, but as:

    PE at start + KE at start + work put in by person or engine – work done against friction = KE at end + PE at end

    “Work done against friction” is really another way of saying “energy lost through friction”

    Work = force×distance moved in the direction of the force

    Power = force×speed, or work per second.

    C4: Work for Friday: Do another six questions from Ex.4F (differentiation).

    Homework: binomial expansion. Finish Ex.3A.

    FP3: Work for Friday: Vector geometry. Finish Ex.5G and do Review Exercise 2 Q.1-6 (p.193).

    Homework: Eigenvalues and eigenvectors – finish Ex.6F.


    Week 4 term 2, due Tuesday 3 February

    M2: Work and energy. Ex.3C Q.5,6,15,17

    If you can’t do these, then look for some other questions in Ex.3C you can do. Or email me for help.

    Remember the work-energy principle *not* the way it is stated in the book, but as:

    PE at start + KE at start + work put in by person or engine – work done against friction = KE at end + PE at end

    “Work done against friction” is really another way of saying “energy lost through friction”

    Work = force X distance moved in the direction of the force

    C4: Differentiation. Do six questions of your choice from Ex.4F

    FP3: vector geometry. Do as many questions as you can from Ex.5G, but at least six.

    FP1 (Lou-Lou and Debora): Do a selection of questions from the complex numbers chapter – about adding, multiplying and dividing complex numbers and about converting between polar (modulus-argument) and rectangular (real-imaginary) form – but *not* about getting roots to equations. (On that, I’ll explain a simpler method than the one in the book, next week).

    FP1 (Dandison): Do the FP1 past paper I gave you.


    Week 3 term 2, due Tuesday 27 January

    FP1 (main class): Parametrics. Review exercises p.70-1, finish off as many as you can of Q.57-66, up to no.62 at least. (Sharif, Dion, Mugisha: you should do at least up to Q.6 of Ex.3F, and at least three of the review exercises on p.70-1.

    C4: Consolidate vectors and start on differentiation. Do three more questions, of your choice, from Ex.5K; and do Ex.4B Q.1 and 2.

    FP3: Using vectors for three-dimensional geometry. Line where two planes meet; angle between a line and a plane; angle between two planes; distance from a point to a plane. Do whatever you have not already done from Ex.5F Q.1-9.

    FP1 (Lou-Lou and Debora and Dandison): do Ex.3A Q.2 and 3, and a selection of your choice from Q.4.



    Week 2 term 2, due Tuesday 20 January

    C4: Vectors. Ex.5H Q.3, 4a, 4b. Ex.5I Q.1,2. Ex.5J Q.1,2

    FP3: Vectors in 3D and cross-product. Ex.5D Q. 1c, 3a, 3b. Ex.5E Q.1c, 3a, 3b, 3c. Ex.5F Q.1a, 1b, 1c, 2a, 2b, 2c.

    FP1 (ordinary class): Parametrics. Finish Ex.3F, at least Q.1-6.

    FP1 (Lou-Lou and Debora and Dandison): Choose some questions on series (Lou-Lou) and induction (Deborah). Do enough questions from the matrices chapter to be confident with it (Dandison).



    Week 1 term 2, due Tuesday 13 January

    C4: Vectors. Finish off Ex.5B and 5C (using displacement vectors and position vectors to do problems in geometry of triangles).

    FP3: Matrices. Do as many questions on inverting matrices as you think you need to be certain you know how to do it. (You decide how many
    that is). Next week we continue on cross product and dot product of vectors.

    FP1 (ordinary class): Parametrics. Finish Ex.3A Q.1 and 2 (drawing the graphs) and Ex.3E p.59, Q.1 to 4 (equations of tangents and normals). The main part of each question is just doing what we did in class about finding dy/dx and the equations of tangents and normals. The last bits of Q.3 and Q.4 need a bit more thought.

    FP1 (Lou-Lou and Debora): Debora to do enough questions on induction with sequences and series to be confident you know how to do them. Lou-Lou to read the chapter on series and do examples from the book to practice.


    Week 13, due Tuesday 9 December

    FP1: Practise matrix multiplying with Exercise 4C, page 81, Q.2-7, and practise matrix addition with Ex 4A, p.75, Q.2, and Ex 4B, p.77, Q. 1-4. (You may want to look at p.76 to help with Ex 4B). Inverting matrices: Ex.4G Q.3, and Ex.4H Q.1-2.

    D1: Linear programming: Ex.6E Q.1-2

    S2: Finish the two S2 past papers, May 2013 and January 2013


    Week 12, due Tuesday 2 December

    FP1: Linear transformations and determinants. Ex.4E Q.1,2,3; Ex.4I Q.1(b) only, Q.4 (a),(b),(c) only

    D1: Linear programming: Ex.6C Q.1-3

    S2: Hypothesis testing: complete and write up the “how random can you get?” survey. This is the assignment sheet with the tallies typed in, and this is the maths on Benford’s Law. See also: these further notes on Benford’s Law.


    Week 11, due Tuesday 25 November

    FP1: In your book, work through the test paper again using the mark scheme and the worked answers and trying to find and fix all the mistakes you made in the actual exam. The mark scheme and worked answers will be available here. If you can’t follow the mark scheme and worked answers for some questions, then email me or ask another student.

    D1: In your book, work through the exam paper again using the mark scheme and trying to find and fix all the mistakes you made in the actual exam. The mark scheme is available here. If you can’t see how the mark scheme gets the answer it does for a question, then email me or ask another student.

    S2: In your book, work through the exam paper again using the mark scheme and trying to find and fix all the mistakes you made in the actual exam. The mark scheme is available here. If you can’t see how the mark scheme gets the answer it does for a question, then email me or ask another student.


    Week 10, due Tuesday 18 November

    Please mark your own work against the back of the book (if you can) before you hand it in. Year 13 students: please leave your books in my blue tray in the maths office on Monday or early Tuesday morning. The blue tray is on the workbench, at the far corner of the office from the door where you come in, under a sign saying “Homework for Martin Thomas” and a photo of my daughters.

    D1: Schedules; matching. Finish Ex.5H Q.1-3. Ex.7B Q.1,2,3. When you do revision for the exam, take note of these “don’t do as the book says” notes.

    S2: Hypothesis testing; continuous random variables. Ex.7D Q.1 and 2, plus four questions from Ex.3E in addition to what you’ve done in class. Plus, use the revision exercises in the book to revise for the exam.

    FP1: Ex.1H, p.29, Q.4, 5, 7, 9. In Q.5 look out for what Mugisha noticed, that you must change the coefficient of x3 to 1 before using the rules about sum and product of roots. In other words, you change the equation to x3−2x2−(5/2)x−(3/2)=0 before using the rules.

    Plus, use the practice sheet to catch up on the areas where you were weak in the test on 17 October. Write your work in your book.

    All: read Tim Gowers’s chapter on proof as a preparation for the sessions on Monday 3 November.

    D1: Chinese postman algorithm, Ex.4C Q.4,5,6; p.81 Q.18, p.85 Q.29

    FP1: Newton-Raphson, Ex.2C Q.1-7, but for each problem just guess an approximate solution and use Newton-Raphson just once to improve the guess. Your answers will be different from the answers in the back of the book.

    Plus, use this practice sheet to catch up on the areas where you were weak in the test on 17 October. Write your work in your book.

    Download pdf.

    S2: Hypothesis testing, Ex.7A, Q.1-7


    Week 7: no homework (half-term)


    Week 6, due Tuesday 14/10/14

    Please mark your own work against the back of the book before you hand it in.

    D1: Chinese postman algorithm, Ex.4C Q.1,2,3

    FP1: Do the remaining series question:

    Show, using the formulae for (sum from r=1 to r=n of r) and (sum from r=1 to r=n of r2), that for all positive integers n:

    sum from r=1 to r=n of (3r−1)2 equals ½n(6n2+3n−1)

    And for each of the following equations, show that the equation has a root in the range mentioned, and do two interval bisections to get a range of ¼ for the answer.

    1. f(x)=x2−8=0 in range [2,3]

    2. f(x)=½x−(1/x)=0 in range [1,2]

    3. f(x)=6x−3x=0 in range [2,3]

    S2: Words to use about sampling. Review Exercise, p.127, Q.6, and p.128 Q.14, page 129 Q.17. Exam practice paper p.131, Q.1


    Week 5, due Tuesday 07/10/14

    Please mark your own work against the back of the book, or the answer sheet, before you hand it in.

    D1: Prim’s algorithm from distance matrix, and Dijkstra’s algorithm – Ex.3E Q.3, 4, 7, 8 (I’ll distribute worksheets for these: please stick them in your book)

    S2: Continuous uniform distribution: Ex.4C Q.1, 2, 3 plus: If you’re still not sure about the normal approximation, do a few more examples from that chapter

    FP1: Series: Ex.5C Q.1, 2, 3 plus: try some problems from this sheet of relatively easy induction examples as practice if you think you need to consolidate induction


    Week 4, due Tuesday 30/09/14

    D1: Kruskal’s and Prim’s algorithms. Ex.3A Q.1(b) and (c), Q.2; Ex.3B Q.1(b) and (c), Q.2

    S2: Binomial approximation to normal. Ex.5B Q.1-4. You’ll need to do the continuity correction: check how to do it from the book.

    FP1: Induction problems with series. Ex.6A Q.3-6


    Week 3, due Tuesday 23/09/14

    FP1: Proof by induction. Do another six questions from the sheet of past exam questions.

    fp1-sequence-and-divisibility-induction-pastq

    S2: Binomial and Poisson distributions. Ex.2F Q.6-10.

    You should also think (for Thursday) about what hypotheses we might test about the patterns when we ask students and teachers to write down a list of 20 numbers between 1 and 999999 chosen at random.

    D1: Bin-packing: Ex.1E Q.3-5. Graphs and trees:

    SCAN0001
    SCAN0000

    Draw a weighted graph (network) representing the following vertices

    A. The main entrance of CoLA

    B. The entrance to the library

    C. The entrance to the hall

    D. The maths office

    E. The Sixth Form Study Area. (For this purpose regard the whole of the Sixth Form Study Area as a single point, and assume you have arrived at that same single point whether you come by the South staircase or the West staircase).

    You should include 15 edges:

    – the routes between the main entrance, the library, and the hall across the ground floor of CoLA;

    – routes via the West and North staircases from all three to the maths office;

    – routes via the West and South staircases from all three to the Sixth Form Study Centre.

    Measure them by pacing them out, and for this purpose assume one pace equals one metre.

    Extra Read https://mathsmartinthomas.wordpress.com/2014/08/23/bin-packing-algorithms/ and write a short summary of it in your notebook.
