Integral of x^-4 dx

You have entered [src]

$$\int\limits_{0}^{1} \frac{1}{x^{4}}\, dx$$

Integral(x^(-4), (x, 0, 1))

Detail solution

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

$\int \frac{1}{x^{4}}\, dx = - \frac{1}{3 x^{3}}$
Add the constant of integration:

$- \frac{1}{3 x^{3}}+ \mathrm{constant}$

The answer is:

$- \frac{1}{3 x^{3}}+ \mathrm{constant}$
