**To prove:** The Simpson’s Rule is exact when approximating the integral of a cubic polynomial function, and also demonstrates the result with

Explanation

**Given Information:**

The given definite integral is

**Formula used:**

Simpson’s Rule:

If *f* is continuous on *n* is an even integer, then

The errors E in approximating

**Proof:**

Consider the definite integral

To prove Simpson’s Rule is exact when approximating the integral of a cubic polynomial function.

Let

The first derivative of

The second derivative of the function is,

The third derivative of the function is,
