1. The problem statement, all variables and given/known data Use Taylor's Theorem to estimate the order of the truncation error in the following approximate formula, when the step size is small: 2. Relevant equations f ' (x) = [-f(x+2h)+8f(x+h)-8f(x-h)+f(x-2h)]/[12h] 3. The attempt at a solution i know that to find the error i need to express the formula in a taylor series, and then i just take the next term and evaluate the derivative at that point. I have no idea how to use the taylor's theorem though.
