Integral of x^-2 dx

You have entered [src]

$$\int\limits_{0}^{1} \frac{1}{x^{2}}\, dx$$

Integral(x^(-2), (x, 0, 1))

Detail solution

The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :

$\int \frac{1}{x^{2}}\, dx = - \frac{1}{x}$
Add the constant of integration:

$- \frac{1}{x}+ \mathrm{constant}$

The answer is:

$- \frac{1}{x}+ \mathrm{constant}$
