Problem 1: Theoretical assignment 1. Use Newton's method to solve x + ell = 0) with an accuracy of 3 decimal places. Please show the specific results at each iterative steps until it converges. (Initial guess Xo = -1). 2. Use Secant method to solve x + ell = 0) with an accuracy of 3 decimal places. Please show the specific results at each iterative steps until it converges. (Initial guess xo = -1, x1 = -1.1). 1 3. Plot absolute value of residual V.S. iterative steps
