4 / | | x | ------ dx | 2 | x - 1 | / 0
$$\int\limits_{0}^{4} \frac{x}{x^{2} - 1}\, dx$$
Integral(x/(x^2 - 1), (x, 0, 4))
Detail solution
We have the integral:
/ | | x | ------ dx | 2 | x - 1 | /
Rewrite the integrand
/ 2*x \
|------------|
| 2 |
x \x + 0*x - 1/
------ = --------------
2 2
x - 1 or
/ | | x | ------ dx | 2 = | x - 1 | /
/
|
| 2*x
| ------------ dx
| 2
| x + 0*x - 1

/
------------------
2 In the integral
/
|
| 2*x
| ------------ dx
| 2
| x + 0*x - 1

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

| ------ du
| -1 + u
|
/ log(-1 + u)
------------ = -----------
2 2 do backward replacement
/
|
| 2*x
| ------------ dx
| 2
| x + 0*x - 1
| / 2\
/ log\-1 + x /
------------------ = ------------
2 2 Solution is:

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