The problem is to show that where g is an odd 2L periodic function and g(L-x)=g(x) I don't understand the following change of variables: But if if the above is true, then it's easy to see that

So we get Now just do the same thing for the bottom limit.
But then the bottom limit would be . What am I not understanding? Wait. If g is 2L periodic, then then an antiderivative of g is also 2L periodic.

Wow. That was a brain fart of epic proportions.
