3. Apply Newton's method to f(x) = x³-5 using initial guess x0 = 1.5. a) Calculate x1, x2, and x3 up to 5 decimal places. b) Do the same calculations using initial guess x0 = 1. c) Find the difference between x3 for the different initial guesses. d) Solve x3 = 5 on your calculator and find the error from your estimate and the actual answer.
