Help with nasty integral

  1. May 22, 2012 #1
    Two types of integrals that are coming up in electrodynamics that I don't know how to do:

    (1-a(1-x^2))^(-3/2) with x as the integration variable.

    And the related and more nasty:

    x*(x^2-a*x+b))^(-3/2)

    What is the formula for doing these?

    Thanks!

    You can do at least the first one with a clever substitution. Sometimes in this kind of problems, substituting first y = 1/x helps.
