is not the best maths book that matters,
I saw many students using the same maths book but get different results,
the question is.....

Are YOU the best student ??

A best book won't make the student to become the best student,
A best student will make every books to become the best book.

I was just looking at some past papers and I'm stuck on this one, top is question and bottom is mark scheme.
First of all, for the integration, I don't get how they got the coefficient of 2 in 2xe^(3x)
I think I really need to brush up on my maths! :eek:
I would really appreciate your help guys! :)

the coefficient of 2 in 2xe^(3x) is because of integration by parts:

Letting u=6x, du = 6
dv=e^(3x), v=(1/3)e^(3x)

then uv = (6x)(1/3)e^(3x), = 2xe^(3x)

and the vdu you calculate yourselves......

There is another way thats easier.. Try inputing the values of x in a table and then draw the graph.. U would b able to visualize more easily
