## Homework Statement

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

## Homework Equations

[tex]\int arcsin x = xarcsinx +\sqrt{1-x^{2}} + C[/tex]

## The Attempt at a Solution

I'm not sure where to begin, when I try to substitute the term inside the brackets the equation gets even more complicated. Help?
