The integral calculator is a tool used to calculate the definite and indefinite integrals of functions. Integrals are fundamental concepts in calculus and are used to determine the area under a curve, the total distance traveled, the volume of a solid, and more. The integral calculator is an essential tool for students and professionals in the fields of mathematics, physics, engineering, and more.

**How to Use the Integral Calculator
**

Using the integral calculator is simple. Here are the steps you need to follow:

- Enter the function you want to integrate in the input field.
- Specify the variable of integration in the “With respect to” field.
- Specify the lower and upper limits of integration in the “From” and “To” fields.
- Click on the “Calculate” button.
- The integral calculator will display the value of the definite integral and the steps taken to solve it.

It’s important to note that the integral calculator may not be able to solve certain integrals. In such cases, the calculator will return an error message.
