Integral(2*x/(1 - x^2), (x, 0, 1))
Detail solution
We have the integral:
/ | | 2*x | 1*------ dx | 2 | 1 - x | /
Rewrite the integrand
2*x -1*2*x + 0
------ = - --------------
2 2
1 - x - x + 0*x + 1or
/ | | 2*x | 1*------ dx | 2 = | 1 - x | /
/ | | -1*2*x + 0 - | -------------- dx | 2 | - x + 0*x + 1 | /
In the integral
/ | | -1*2*x + 0 - | -------------- dx | 2 | - x + 0*x + 1 | /
do replacement
2 u = -x
then
the integral =
/ | | 1 - | ----- du = -log(1 + u) | 1 + u | /
do backward replacement
/ | | -1*2*x + 0 / 2\ - | -------------- dx = -log\-1 + x / | 2 | - x + 0*x + 1 | /
Solution is:
/ 2\ C - log\-1 + x /
The answer (Indefinite)
[src]
/ | | 2*x / 2\ | ------ dx = C - log\1 - x / | 2 | 1 - x | /
$$-\log \left(1-x^2\right)$$
