1. Suppose the data in the table was taken from the function f (x) = xcos(x) – x² sin(x). Find the truncation error for forward difference. www O 16.15 4.1 4.2 O 16.45 O 17.15 f(x) 3.5 3.7 3.9 O 17.45 2. For a function f (x) = x*, what will be the approximate truncation error in terms of h for x-2 and h=1 using central difference? 1.
