Doing the following integral

  1. Feb 16, 2007 #1
    I haven't done basic integrals for awhile...but just wondering how you would integrate the following functions without looking it up in the integral table.

    (x^2+a^2)^(-3/2) where a is a constant.

    Thanks!

    Make the substitution [itex] x=a\sinh t [/itex] and then see what you get.

    The substitution [itex]x= atan(\theta)[/itex] will also work.
