The integral calculator helps you compute the integral of a given function over a specified interval. This tool is especially useful for students, engineers, and professionals who need to perform complex integrations quickly and accurately.
Integral Calculation Formula
The integral of a function f(x) from a to b is calculated using the formula:
∫[a, b] f(x) dx
Variables:
 ∫ represents the integral sign
 a and b are the lower and upper limits of integration, respectively
 f(x) is the function to be integrated
 dx indicates the variable of integration
To calculate the definite integral of a function f(x) over an interval [a, b], follow these steps:
 Determine the function f(x) to be integrated.
 Identify the lower limit a and the upper limit b of the integral.
 Apply the integral formula: ∫[a, b] f(x) dx.
 Use an integral calculator or analytical methods to find the value of the integral.
What is Integral Calculation?
