(8.2.e) Derive an iteration using Nonlinear Gauss-Seidel-Newton (one-step) to solve the system of two nonlinear equations above. (8.2.f) Implement it and consider the performance for a variety of initial conditions to solve the system of two nonlinear equations above. (8.2.g) Compare to the work required to achieve a given accuracy Nonlinear Jacobi-Newton and Gauss-Seidel-Newton, and Newton’s Method when starting at the same initial condition? Also compare to iterations 1 and 2 in the latest program-ming assignment. Note you do not have to turn in any implementation. This is not a programming assign-ment. 1...
