**[SOLVED] Find integral of sqrt((1-x)/(1+x))**

## Homework Statement

[tex]\int\sqrt{\frac{1-x}{1+x}}dx[/tex]

## Homework Equations

## The Attempt at a Solution

I have started by multiplying by [tex]\sqrt{1-x}[/tex] in the numerator and denominator. Then I separated the two fractions to get

[tex]\int\frac{1}{1-x^2}dx[/tex][tex] -\int\frac{x}{1-x^2}dx[/tex] I'm stuck here! Any help is greatly appreciated!
