Definite and Improper Integral Calculator

Calculate definite and improper integrals step by step

The calculator will try to evaluate the definite (i.e. with bounds) integral, including improper, with steps shown.

Enter a function:

Integrate with respect to:

Enter a lower limit:

If you need `-oo`, type -inf.

Enter an upper limit:

If you need `oo`, type inf.

Please write without any differentials such as `dx`, `dy` etc.

Solution

Your input: calculate $$$\int_{0}^{7}\left( \frac{x^{4}}{7} \right)dx$$$

First, calculate the corresponding indefinite integral: $$$\int{\frac{x^{4}}{7} d x}=\frac{x^{5}}{35}$$$ (for steps, see indefinite integral calculator)

According to the Fundamental Theorem of Calculus, $$$\int_a^b F(x) dx=f(b)-f(a)$$$, so just evaluate the integral at the endpoints, and that's the answer.

$$$\left(\frac{x^{5}}{35}\right)|_{\left(x=7\right)}=\frac{2401}{5}$$$

$$$\left(\frac{x^{5}}{35}\right)|_{\left(x=0\right)}=0$$$

$$$\int_{0}^{7}\left( \frac{x^{4}}{7} \right)dx=\left(\frac{x^{5}}{35}\right)|_{\left(x=7\right)}-\left(\frac{x^{5}}{35}\right)|_{\left(x=0\right)}=\frac{2401}{5}$$$

Answer: $$$\int_{0}^{7}\left( \frac{x^{4}}{7} \right)dx=\frac{2401}{5}\approx 480.2$$$
