Simpson's Rule and Fourth Derivatives

The video tutorial explains how to estimate the definite integral of cosine 4x from -1 to 4 using Simpson's Rule with n=10. It covers the error bounds formula and demonstrates how to calculate the error by finding the maximum value of the fourth derivative on a closed interval. The tutorial includes both analytical and graphical methods to determine this maximum value, ultimately showing that the error is less than or equal to 4/9.
