Let f(x) = e* sin x. Using the forward 2-point formula for Ist derivatives with truncation error 1: f'(0) - 0.6526 using h = 0.4 f'(0) z 0.8133 using h = 0.2 Applying Richardson's extrapolation on the above values, we get a better approximation of f'(0) which is: 0.9740 None of the answers This option This option 0.9897 0.9598
