Area Between Two Curves Calculator: Find the Region Between Functions

Calculate the Area Enclosed by Two Functions

Enter your function f(x) using valid JavaScript syntax (e.g., Math.pow(x,2), x*x, Math.sin(x)).
Enter your function g(x) using valid JavaScript syntax (e.g., Math.pow(x,2), x*x, Math.cos(x)).

Utilize our Area Between Two Curves Calculator to quickly determine the exact area enclosed by two functions over a specified interval. Simplify complex calculus problems and visualize the region between curves with ease. Get accurate results for your academic or professional needs, understanding the definite integral concept.

Formula:

A = ∫ab |f(x) - g(x)| dx

Where:

  • A = The calculated area
  • f(x) = The first function
  • g(x) = The second function
  • a = The lower limit of integration
  • b = The upper limit of integration

The calculator approximates the definite integral of the absolute difference between the two functions over the given interval [a, b].
