A maths problem involving Riemann intergrals

[fylth]

I've been having some trouble with a maths problem and I hoped someone might be able to help.

We don't seem to have been taught most of what we need to do this, I understand Riemann integrals but what we've been taught and what they're asking for is just different.

Thanks for any help anyone can provide, I looked for some kind of maths subforum but I didn't see one

Shouldn't the left integral be definite?

if the left integral is meant to be between b an a I think I solved it in the maths thread

Aha, didn't see that, thankyou :)

I feel ashamed that I don't understand this. At all. Damn, I wish I could do maths well.
