Like, when it says...
1/2 x width (1st height + 2(sum of middle heights) +last height) the numbers in brackets are mixed with last height or first height :/

If it is just that first height and last height are the opposite way around, then it won't effect the answer.

You should do it as per attachment though, so ignore that they've done it differently in the mark scheme.

I get that bit, okay also what's the step bit

After like 9 papers!!! I got 73/75... Thank You January 2011 and everyone in this thread

[L'Evil Fish]

On January 2011 the very last question, I don't understand how I got the answer using tan I don't know WHY I used it... It worked though, could you explain? The area of t he triangle (I got the sector with understanding)

How embarrassing, I Do know why I used it... It's a right angles triangle :P

Thanks for the resources... I've done every C2 past paper now
I went from about 50 on the first paper to 73 on the last paper thank you!!

Slowly finishing C3, what do I need to know, as I'm using an edexcel book...

If you can list the chapters for C3 that are in the Edexcel textbook, then I should be able to help. You might need to go to C4 and check some of those, you see.

C3:
Algebra
Functions
Trigonometry
Differentation
Numerical Methods
Proof

I know I need integration as well for C3 but to what degree?

You'll need to know the integral of standard functions and be able to use the chain rule backwards (i.e. integration by recognition).

For trigonometry, you need to know the trigonometric graphs and identities as well as being able to differentiate the six trigonometric functions.

You'll need to know exponential and logarithms. This will be the definitions and graphs for e^x and ln(x). Knowing their derivatives.

For functions, you'll need to know what is meant by domain and range. Be able to form composite functions and solve equations from this. Find the inverse function.

You'll need to know modulus functions, their graphs and inequalities.

For differentiation, you'll need to know the chain, product and quotient rule. Implicit and parametric differentiation. Be able to differentiate inverse trigonometric functions. Know what is meant by principal solution. Sketch their graphs.

Numerical Methods is knowing how to use the Simpson's Rule.

All proofs are given in resource sheets.

The above is all you need to know.

Of that, what is needed for M2?

This is what I said was needed for M2.

For M2, you'll need to have extensive knowledge of much of the following: chain rule, product rule and quotient rule (C3); differentiation and integration of trigonometry functions, logarithms and exponential (C3); vectors (C4); trigonometry - compound angle formulae, double angle formulae and the 'R' method (C4); direct integration - by recognition, parts and substitution (C4); algebraic and partial fraction (C4).

As you can see, it's mainly having a solid grasp of the differentiation and integration. Including with respect to trigonometry, logarithms and exponential.

Oh yes, thanks a lot! What is the R method?

We use the 'R' method to rewrite sums or subtraction of two functions into a single function. It's one of the easiest topics you'll do in C4, but just requires a bit of practice.

Okay thanks I have a headache since fasting so, I'm not learning much not effectively... So..

Can someone put in order of difficulty these modules
C1 < C2 < S1 < M1 < FP1 < C3 < C4 < S2 < M2 < M3 < FP2 < FP3

It'll be subjective and so I don't see the point in ordering them for you, but the order in which you've given them in your post isn't far removed from what I would list.

Okay I've sort of jumbled everything up in my head... I think I need to start C3 again, fresh! I'll go back to M1 for now, so I at least have my AS done and ready

Guys! Who's done S1, can you give me a list of what to study for it..

Poisson Distribution
Binomial Distribution
Etc

Thanks
