Problem 2) Compute the backward difference approximation of O(ha) for the first derivative of y = sin x at x = 7/4 using a value of h = 7/12 and determine the true percent relative error et. Take the exact value of the derivative at #/4 to be cos (1) (1) = 0.70710678. The values of f(x) at the points Xi, Xit1 = x; h, Xi+2 = Xi 2h, are given below.
