Convergence. Let f(x)= x + 2x-3x -4 = 0. Write this as choosing (1) (x - f(x)), (2) (x (x)), (3) x + (x), (4) (x - f(x))/x, (5) (2x -f(x))/(2x) and in each case xo = 1.5. Find out about convergence and divergence and the numbers of steps to reach 10-6 accuracy of a root. = g(x), for g(x) X = Interval Bisection method and Newton's method. Solve x = cos x by Newton's method and by Interval bisection method. Compare them.
