I'm having a hard time doing this problem.

(Tan^-1(x)) / 1 + x^2

I'm know i'm gonna have to use the substitution rule

I designated

u = arctan

du = 1 / (1 + x^2) dx

From here i'm fairly stuck. Any help is appreciated

At least we explained why :D

We already discussed about that, it's no competition :) - Apr 24th 2008, 12:41 PMo_O
