Definite Integral Calculator

Calculate the Definite Integral of a Function

Use * for multiplication (e.g., 2*x), ** for powers (e.g., x**2 or x^2). Supported functions: sin(), cos(), tan(), log(), sqrt(), abs(), exp(), PI, E.
Higher numbers increase accuracy but also computation time. Must be an even number for Simpson's Rule.

Our Definite Integral Calculator simplifies complex calculus problems, helping you find the area under a curve quickly. Input your function (f(x)), lower limit (a), and upper limit (b) to get instant, accurate results. Ideal for students, engineers, and anyone needing quick integral calculations for academic or professional tasks. Master calculus with ease!

Formula:

The definite integral of a function f(x) from a to b is represented as:

ab f(x) dx

Where:

  • f(x): The function to integrate (e.g., x^2, sin(x), log(x))
  • a: The lower limit of integration
  • b: The upper limit of integration
  • dx: Denotes integration with respect to x
