Homework Help: Partial fractions integral

  1. Sep 21, 2010 #1
    1. The problem statement, all variables and given/known data

    integral of: 1/(((L2)/4)+y2)

    This is for proving the flux through a cube from a wire going through it is = Qenc/epsilon0

    All that's left for one face after taking out constants is the above equation, and I really don't want to go re learn how to do partial fractions again. Any help?

    Use a trig substitution, rather than partial fractions.
