Symbolab Integration Calculator

Integration is a fundamental concept in calculus that represents the accumulation of quantities. This calculator helps you solve both definite and indefinite integrals using the Symbolab integration method, providing accurate results and step-by-step solutions.

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. There are two main types of integration:

Indefinite Integration: Finds the antiderivative of a function, which represents a family of functions.
Definite Integration: Calculates the exact area under the curve between two specified limits.

The Symbolab integration method uses advanced algorithms to solve integrals symbolically, providing exact solutions when possible and numerical approximations when exact solutions are complex.

How to Use This Calculator

Enter the function you want to integrate in the input field.
Select whether you want to solve an indefinite or definite integral.
If solving a definite integral, enter the lower and upper limits.
Click the "Calculate" button to get the result.
Review the solution and chart visualization if available.

For best results, enter functions in standard mathematical notation. The calculator supports basic arithmetic operations, trigonometric functions, exponentials, and logarithms.

Formula Used

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

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

The Symbolab integration calculator uses advanced symbolic computation techniques to find the antiderivative F(x) of the input function f(x). For definite integrals, it evaluates the antiderivative at the upper and lower limits and subtracts the results.

Worked Examples

Example 1: Indefinite Integral

Find the indefinite integral of x².

∫x² dx = (1/3)x³ + C

Using the calculator, enter "x^2" as the function and select "Indefinite Integral". The result will be (1/3)x³ + C.

Example 2: Definite Integral

Calculate the area under the curve of x² from x=0 to x=2.

∫[0 to 2] x² dx = (1/3)(2)³ - (1/3)(0)³ = 8/3 ≈ 2.6667

Enter "x^2" as the function, select "Definite Integral", and set the limits to 0 and 2. The calculator will return 8/3 as the result.
