(adsbygoogle = window.adsbygoogle || []).push({}); 1. The Problem comes down to what I think is a fairly simple integral, I just can't figure it out.

int(x^2/(1+x^2)

I know this is x-arctan(x)+c, but cannot figure out how.

I tried subbing in u for x^2, this didn't really help me with a direction to take though.
