the problem asks for the area under the shaded region of the line y = 1/(1-x^2) on the interval [-1,1].(adsbygoogle = window.adsbygoogle || []).push({});

so far i've set up the integral showing

\int [tex]dx/(1-x^2)[\tex]

on the interval [-1,1]

i'm pretty sure you have to use substitution to solve it, but i cant seem to figure it out

please show/describe each step to solve it.
