  1. Aug 20, 2012 #1
    1. The problem statement, all variables and given/known data
    I am suppose to rearrange the integral in order to use this formula to solve it:

    2. Relevant equations
    My integral is ∫(e^x+1)/(e^x+e^-x+2).

    3. The attempt at a solution
    Any help?

    To simplify the integral, let ##y=e^x## and break it into partial fractions.

    Write e^(-x) as 1/(e^x). Simplify and you should get the expression:
    Can you now see which is f(x) and which is f'(x)?
