What is an Integral Calculator?

An integral calculator is a computational tool that evaluates integrals of mathematical functions. Integrals represent the area under a curve and have applications in physics, engineering, economics, and many other fields.

This calculator provides both definite and indefinite integrals, with results formatted to match TI-83 output. It includes:

Step-by-step solutions for many common functions
Graph visualization of the function and its integral
Support for basic and advanced mathematical functions
Clear formatting of results similar to TI-83 output

How to Use the Integral Calculator

Enter the function you want to integrate in the function field
Select whether you want a definite or indefinite integral
For definite integrals, enter the lower and upper bounds
Click "Calculate" to compute the integral
Review the result and graph visualization

Note: This calculator supports basic mathematical functions like sin(x), cos(x), e^x, x^n, ln(x), and more. For complex functions, results may be less precise.

Types of Integrals

Indefinite Integrals

Indefinite integrals find the antiderivative of a function, represented as ∫f(x)dx. The result includes a constant of integration (usually +C).

Definite Integrals

Definite integrals calculate the area under a curve between two points, represented as ∫[a to b] f(x)dx. The result is a single numerical value.

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

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

Common Integral Formulas

Here are some fundamental integral formulas that this calculator can evaluate:

Function	Integral
x^n	(x^(n+1))/(n+1) + C (n ≠ -1)
sin(x)	-cos(x) + C
cos(x)	sin(x) + C
e^x	e^x + C
1/x	ln\|x\| + C

Example Calculations

Example 1: Indefinite Integral

Calculate ∫x²dx

Using the formula for x^n: ∫x²dx = (x³)/3 + C

Example 2: Definite Integral

Calculate ∫[0 to 1] x²dx

First find the antiderivative: ∫x²dx = (x³)/3 + C

Then evaluate from 0 to 1: [(1³)/3] - [(0³)/3] = 1/3 - 0 = 1/3
