Consider the root of function f(x) = x 3 − 2x − 5. The function can be rearranged in the form x = g(x) in the following three ways: (a) x = g(x) = x3 − x − 5 (b) x = g(x) = (x 3 − 5)/2 (c) x = g(x) = thirdroot(2x + 5) For each form, apply fixed-point method with an initial guess x0 = 0.5 to approximate the root. Use the error tolerance = 10-5 to...

In MATLAB write a function secant.m to apply the secant method. function [x,i] = secant(f, x0, x1, tol, maxiters) [x,i] = secant(f, x0, x1, tol, maxiters) performs the secant method with f(x), starting at x_0 = x0 and x_1 = x1, and continuing until either |x_i+1 - x_i| <= tol, or maxiters iterations have been taken. The number of iterations, i, is also returned. An error is raised if the first input is not a function handle. A warning is...
