My question is really just a clarification. When using the Simpson's error equation to determine the value of n needed to produce a certain level of accuracy, you take the maximum absolute value, right? So for instance, that means that for this problem:
the maximum value of on [-1,2] is the minimum of the function on that interval, at x = 0. So for
you use K = 3, right? Or do you use the actual maximum itself? (In the example, about at x = 0.866 or -0.886.) Thanks for the help!
