1. just wondering what the next step would be

i guess it would be -x^6 on top of the next fraction, but i dunno about on the bottom?
2. What...?

Do you want to evaluate the integral because you are effectively there...
3. If you have then you do .

So it's .

Ah. Well, that general rule is:

(for n not equal to 1).

In your case n = 5, so insert this into the formula, remembering the multiplier of 4 and then use my post above.

Maths repulses me.
6. i think i get it, i don't think my lecture notes help at all
can't see where the other numbers came from in the example they use

would they just come out as -42?
or 64
i'll take -42 as the post below says
7. yep

GA do you know how to derive it? I know it should involve Riemann sum notation.

I can do it using inequalities (there was an old question on find x^5; it could be easily generalized for x^n), not sure about Riemann sum notation, though. [Actually, the aforementioned question is a definite integral between 0 and 1, but I think that's fixable.]

*stabs*

n not equal to -1.

n not equal to -1.
Oh, oops.
