## Simpsons Rule Calculator

Are you looking for an easy way to calculate integrals using Simpsons Rule? Look no further – our Simpsons Rule Calculator is here to help! Whether you’re a student studying calculus or a professional in need of quick and accurate integration calculations, our calculator is designed to simplify the process for you. Simply input the function you want to integrate, the lower and upper limits of integration, and the number of subintervals you’d like to use – our calculator will do the rest for you.

## How Simpsons Rule Works

Simpsons Rule is a numerical method for approximating the value of a definite integral. It works by dividing the area under a curve into a series of trapezoids and then approximating the area of each trapezoid using a quadratic polynomial. By summing the areas of these trapezoids, Simpsons Rule provides an estimate of the integral’s value.
