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

2 do replacement
2 u = x
then
the integral =

| -4 + u
|
/ log(-4 + u)
------------ = -----------
2 2 do backward replacement

The answer (Indefinite)
[src]
/ | / 2\ | x log\-4 + x / | ------ dx = C + ------------ | 2 2 | x - 4 | /
$$\int \frac{x}{x^{2} - 4}\, dx = C + \frac{\log{\left(x^{2} - 4 \right)}}{2}$$
