Online Integration Calculator Symbolab

Integration is a fundamental concept in calculus that represents the accumulation of quantities. This online integration calculator with Symbolab integration provides a powerful tool for solving definite and indefinite integrals, with step-by-step solutions and graphing capabilities.

What is Integration?

Integration is the reverse process of differentiation. While differentiation calculates rates of change, integration finds quantities accumulated over an interval. It has applications in physics, engineering, economics, and many other fields.

There are two main types of integrals: definite integrals and indefinite integrals. Definite integrals calculate the net accumulation over a specific interval, while indefinite integrals find the family of functions that have a given derivative.

Key Concept

The Fundamental Theorem of Calculus connects differentiation and integration, stating that differentiation is the inverse operation of integration.

Types of Integrals

Indefinite Integrals

Indefinite integrals represent the antiderivative of a function and are written with a constant of integration (C). They express the general solution to a differential equation.

∫f(x) dx = F(x) + C

Definite Integrals

Definite integrals calculate the net accumulation of a function over a specific interval [a, b]. They represent the area under the curve between these limits.

∫[a,b] f(x) dx = F(b) - F(a)

Improper Integrals

Improper integrals extend the concept of integration to infinite limits or functions with infinite discontinuities. They require special techniques like limits to evaluate.

Common Integration Formulas

Here are some fundamental integration formulas that are useful for solving a wide range of problems:

∫x^n dx = (x^(n+1))/(n+1) + C (n ≠ -1) ∫e^x dx = e^x + C ∫a^x dx = (a^x)/ln(a) + C ∫sin(x) dx = -cos(x) + C ∫cos(x) dx = sin(x) + C ∫sec²(x) dx = tan(x) + C ∫csc(x)cot(x) dx = -csc(x) + C ∫sec(x)tan(x) dx = sec(x) + C

These basic formulas form the foundation for more complex integration problems. Many functions can be integrated by combining these basic forms.
