2) With the user-friendly program developed on the course site to obtain the first derivative estimates for unequally spaced data. If the function is y = x+5xex at x = 3 using step size of h = 0.006 a Forward difference approximations of O(h): b) Bacward difference approximations of O(h): c) Central difference approximations of O(h2): d) Central difference approximations of O(h):
