Integration Calculator Symbolab

Integration is a fundamental concept in calculus that represents the accumulation of quantities. Symbolab's integration calculator provides a powerful tool for solving both definite and indefinite integrals with step-by-step solutions and visualizations.

What is Integration?

Integration is the reverse process of differentiation. While differentiation finds the rate of change of a function, integration finds the area under the curve of a function or the total accumulation of a quantity.

There are two main types of integration:

Indefinite Integration: Finds the antiderivative of a function, which includes a constant of integration.
Definite Integration: Calculates the area under the curve between two points, providing a numerical result.

Basic Integration Formula:

∫f(x)dx = F(x) + C (Indefinite Integral)

∫[a to b] f(x)dx = F(b) - F(a) (Definite Integral)

Integration has numerous applications in physics, engineering, economics, and many other fields where accumulation of quantities is important.

Integration Examples

Example 1: Indefinite Integral

Find the integral of x² + 3x + 2.

∫(x² + 3x + 2)dx = (1/3)x³ + (3/2)x² + 2x + C

This example demonstrates how the calculator handles polynomial functions by integrating each term separately and combining the results.

Example 2: Definite Integral

Calculate the area under the curve of sin(x) from 0 to π.

∫[0 to π] sin(x)dx = 2

This example shows how the calculator evaluates definite integrals, providing both the exact result and a graphical representation of the area under the curve.
