|-
|Note how much less "error" area that there is. This graph represents the first parabola we use for Example 2 Continued.
|-
|The parabola evaluates the integral from 4 to 6.
|-
|By reducing the area that each individual parabola approximates, our total approximation becomes more accurate.

As our estimation was quite off, we should use the Composite Rule to get a better approximation.
<br />For this example, we will use 8 subintervals.
