Integration - get a 991es to check, but only use it to check, you must show all your working

Was just wondering what exactly can a 991es do that most others can't? Both in C2 and other modules?

Thanks for thread by the way :biggrin:

Arsey has posted a solution to this paper on the first page of this thread.

Draw a sketch of the problem with what you already know.
You should see that you can form an isosceles triangle from the centre to points P & Q, you need to find the length of AB which is the radius of the circle and half it (since it's the midpoint that the new line crosses) then it's very basic circle theorem/triangle stuff for the rest.

Which ones are you having problems with? If you tell me which ones confuse you I can give help but I don't want to just post up the solutions as it's unconstructive :smile:

The first one is a pretty standard differentiate problem, even if you can't do parts a & b you can use the given equation and the rest should be very straightforward.
The other 3 are in the Heineman text book in the mixed exercises from the relevant chapters.
If you don't have the book, post your answers and I'll check if they are correct.

Yes Please: The algebra in chapter 1,Trigonometry and rads, series & sequences, co-ordinate geometry,integration & differentiation

No Thanks: Hard logs questions, logs in sequences & series(prooving such and such > such an such) and tricky trig equations.

85 UMS would be ideal I think. I scored just below 90UMS on S1 by the looks of things, hopefully I'll get dead on 90 though :smile:

Hi, Arsey

You know you posted some revision notes for the S1 exam!
Would you be able to do the same for this C2?
They were very helpful!

Cheers

I seriously hate questions where you get given a diagram of a cylinder or a cube and you have to prove that the area/volume is equal to a certain formula. I just can't do them :frown:
