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

2 u = x
then
the integral =

| -1 + u
|
/ log(-1 + u)
------------ = -----------
2 2 do backward replacement

| x + 0*x - 1
| / 2\
/ log\-1 + x /
------------------ = ------------
2 2 Solution is:
C + log(1 + x)
The answer (Indefinite)
[src]
/ | | x - 1 | ------ dx = C + log(1 + x) | 2 | x - 1 | /
$$\int \frac{x - 1}{x^{2} - 1}\, dx = C + \log{\left(x + 1 \right)}$$
