Okay, so what are we doing? The integral, the sum or what limit?

That is okay, the first one looks like Rolle's or Mean Value might do it, I will post if I get something.

Hi Yusuke00

If f(a)>g(a), then h(x)=f(x)-g(x), otherwise, h(x)=g(x)-f(x). We can see that it is true that h(a)<0 and h(b)>0. Then, we can apply the theorem given here.
