## 2 Ways For Simpsons 3/8 Rule in C Programming

Let’s understand the Simpson’s 3/8th rule method in numerical analysis and implement Simpsons 3/8 Rule in C programming language. You will get an overall idea about Simpson’s rule here.

#### What is Simpsons 3/8 Rule?

The Simpson’s 3/8th rule was developed by a mathematician named Thomas Simpson. Integration is the process of measuring the area under a function plotted on a graph.

The Simpson’s 3/8th rule is used in complex numerical integrations. This integration method uses parabolas to approximate each part of the curve. It is basically used to measure an area in a curve.

The Simpson’s 3/8th method is used for uniformly sampled function integration purpose. The Simpson’s 3/8th integration method is primarily used for numerical approximation of definite integrals.
