Partial fraction of integrand

  1. Nov 25, 2004 #1
    As part of finding the integral of z/(z^2 -1), I'm stuck on getting the partial fraction for it. 1/2 [(1/(z-1) - 1/(z+1)] gives 1/(z^2-1). What should I do to get the z in the numerator. Any hints welcome.

    Assume you have a, b where


    Solve for a and b anyway you like.
