Consider the function f(x) = cos x - 3x + 1. Since f (0)f () <0, f(x) has a root in [0, 1]. To solve f(x) = 0 using fixed-point method, we may consider the equivalent equation x = (1 + cos x). Let g(x) = (1 + cos x). Since lg'(0)| < 1, the fixed-point iteration xn = g(xn-1), with xo = 0, will converge. What is x4? (Answer must be in 8 decimal places)
