No posts eh? Not surprising given the exam takes place so late. Do u have any notes about/ or can u explain PROOF BY INDUCTION? Thanx...and what exactly will be required from the matrix chapter...only addition, mulitplication and inverse, ryt? NO transformations?

Just stupidity on my part, worked it out and it was pretty easy...I looked at the ms before but didn't get what it was doing, all is well now though :)
Just for part C, it's clear that you have to differentiate because it asked for a minimum value :P But I don't see why you'd actually do it in the first place =/  (What's the theory behind it?)
Thanks in advance

I understand what to do but I don't know why.
Doesnt differentiating have stuff to do with gradients and things rather than distances?

Differentiate whenever you want to find a max or min

It's good to bring the river to those feeling thirsty. Nice initiative.

Theres a specimen paper I need the markscheme for but I can't seem to find it ANYWHERE :(
I dunno how to explain which one it is...It says 2003 at the bottom and here are some slight descriptions of the questions.
Its for FP1 by the way (but most questions are FP2)

1.sigma notation Q
2. has a lnx in it and part b is newton raphson procedure
3. inequalities Q
4. roots of a cubic equation. find P
5. about a bank

I'd really appreciate it if anybody could find the markscheme, thanks :)
