I want to compute $ \int \frac{1+x^2}{1-x^2} dx $
I am not sure how to do this one. I need some suggestions please. By the way, I need to integrate this for homework.
I appreciate your help!

rewrite it as \begin{align*} \frac{1 + x^2}{1-x^2} &= -1 + \frac{2}{1 - x^2}\\ &= -1 + \frac{1}{1 - x} + \frac{1}{1 + x}\\ \end{align*} I'm sure, you can integrate this.
