Homework Help: Integration help needed

  1. Feb 9, 2005 #1
    4/(e^x - 2)^2

    That was a test question that I had tonight...solutions wont be up for a while, wondering how to approach it.

    I thought of expanding the bottom bracket, then multiplying by (e^x)/(e^x), substituting u=e^x and then using partial fractions...not sure if it is right, thanks in advance.

    Yes,i would have done it the same way:multiply both the numerator & the denominator with the e^{x} and then make the obvious substitution e^{x}---->u and then use partial fractions.
