Practice Exercise #1 Find the (a) true error, (b) relative I CAN'T true error, (c) absolute relative STOP true error of the following: THINKING!! 1. The derivative of f (x) = x3 + 2x + 1 at x = 0.5 2 when h = 0.005 2. The derivative of f (x) = X 7ez at x = 2 when h = 0.3 Property of STI IT1903 Week 2Practice Exercise #2 Find the (a) approximate error, (b) I CAN'T relative approximate error, (c) absolute relative approximate error STOP of the following: THINKING!! 1. The derivative of f (x) = x3 + 2x + 1 at x = 0.5 2 when hcurrent = 0.005 and 2 hprevious = 0.05 Property of STI IT1903 Week 2Practice Exercise #2 Find the (a) approximate error, (b) I CAN'T relative approximate error, (c) absolute relative approximate error STOP of the following: THINKING!! 2.
