定积分与广义积分计算器

逐步计算定积分和广义积分

该计算器将尝试计算定积分（即带上下限的积分），包括广义积分，并显示求解步骤。

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.

Your input: calculate $$$\int_{- \frac{\pi}{2}}^{\frac{\pi}{2}}\left( \frac{1}{\cos{\left(x \right)}} \right)dx$$$
