Calculadora de Integrais Definidas e Impróprias

A calculadora tentará calcular a integral definida (isto é, com limites), inclusive no caso impróprio, com os passos mostrados.

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.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Solution

Your input: calculate $$$\int_{0}^{\pi}\left( 5 \sin{\left(x \right)} \right)dx$$$

First, calculate the corresponding indefinite integral: $$$\int{5 \sin{\left(x \right)} d x}=- 5 \cos{\left(x \right)}$$$ (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.

$$$\left(- 5 \cos{\left(x \right)}\right)|_{\left(x=\pi\right)}=5$$$

$$$\left(- 5 \cos{\left(x \right)}\right)|_{\left(x=0\right)}=-5$$$

$$$\int_{0}^{\pi}\left( 5 \sin{\left(x \right)} \right)dx=\left(- 5 \cos{\left(x \right)}\right)|_{\left(x=\pi\right)}-\left(- 5 \cos{\left(x \right)}\right)|_{\left(x=0\right)}=10$$$

Answer: $$$\int_{0}^{\pi}\left( 5 \sin{\left(x \right)} \right)dx=10$$$
