# Integral problem: need help landing this

The problem is to find the definite integral of e^2x/(e^x + e^-x) with the limits of 0 and log 2. Finding the integral was easy enough, e^x - log (1 + e^2x) , but how do I plug log 2 into this. Any hints appreciated.

Hints:

$$e^{\log x} = x$$
$$e^{a\log x} = x^a$$
