I am reading Mark Newman's(adsbygoogle = window.adsbygoogle || []).push({}); Computational Physicstextbook. He goes over calculating integrals with Simpsons's Rule and the Trapezoidal Rule, and then he goes over calculating their errors. Why would I have to ever worry about the error of the integral?

He has the chapters online at his website:

He begins to go over this in chapter 5 on page 150.
