# Higher Maths 2010 Question Help watch

1. Have been doing the 2010 paper 2 for higher maths today

Does anybody know how to do question 5, I know how to work out the area between 2 curves or a curve and a straight line but this question I have never seen before.

Heres a Link to that paper

Thanks for any help.

2. How much of the question have you done? (note this question doesn't require any integrating)
3. I tried doing it by integration and then just got myself confused so havent actually done any of it.
4. The 8x is the vital bit at first. First find a value of p that will give you an 8x when you expand out the brackets. Then the value of q should jump out at you.
5. sorry but the 8x is in question 5 of paper 1, you have to scroll down to paper 2 , sorry i didn't make that obvious, i know how to do that question 5

Ahh, I fail, sorry.

As for your question, there are several steps:

1) find the y coordinate of T
2) find the y coordinate of Q
3) then PQ is 2)-1)

The maximum thing then follows by differentiating A with respect to x.
7. thanks, understand how to do it now, it's one of those questions that once you have an idea of how to do it, you realise you can do it.
