This free online Integration Calculator solves both definite and indefinite integrals. It supports common functions like polynomials, trigonometric, exponential, and logarithmic functions. Enter your expression and let the calculator find the antiderivative or area under the curve.
📘 What Is Integration?
In calculus, integration is the process of finding the integral of a function. The integral of a function gives the area under the curve of that function. It is the reverse process of differentiation.
🔣 Basic Integral Formula
If F(x) is the antiderivative of f(x), then:
∫ f(x) dx = F(x) + C (Indefinite Integral)
∫ab f(x) dx = F(b) − F(a) (Definite Integral)
