An Integral problem: need help

  1. Apr 29, 2008 #1
    This is my first post so bare with me plz.

    What is the integration of DX/(x^2+1)^(3/2)

    The (3/2) is the power of the bigger parenthasis. The dx is on top, and the rest of the problem is on bottom.

    [tex]\int \frac{1}{(1+x^2)^\frac{3}{2}}dx[/tex]

    If you have something like that usually what you should do is see if integration by parts will help and if that doesn't help,look for a substitution.
    Try substitution x as some trig function.
