Techniques of numerical integration have been developed because of the following reasons:

- Integration, in general, is a difficult operation.
- We may have experimental data, but we may not know the actual function generating those values.

In this article, we will discuss 3 commonly used numerical integration techniques, the trapezoidal rule, Simpson’s 1/3rd rule and Simpson’s 3/8th rule.

- Uses the single degree curve for integration

This rule is also known as Simpson’s rule.

- Uses a second degree curve for integration.

- It uses a third degree curve for integration
