$$\int\limits_{0}^{1} \frac{x}{1 - x^{2}}\, dx$$
Integral(x/(1 - x^2), (x, 0, 1))
Detail solution
We have the integral:
/ | | x | ------ dx | 2 | 1 - x | /
Rewrite the integrand
-2*x
- --------------

x - x + 0*x + 1
------ = -----------------
2 2
1 - x or
/ | | x | ------ dx | 2 = | 1 - x | /

2 do replacement
2 u = -x
then
the integral =
