Integrating DX/(x^2+1)^(3/2): Solving an Integral Problem

[Cy4NidE]

This is my first post so bare with me please.

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.

\int \frac{1}{(1+x^2)^\frac{3}{2}}dx

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.

try to substitude x=tan z
