Use fixed-point iteration to locate the root of f(x) = cos x - x² Use an initial guess of co 0.5 and iterate until a < 0.01%. Display graphically the approximate solutions and relative errors in each iteration steps. (b) [10 points] Use the Newton-Raphson method to determine a root of f(x) = -9x² +1.6√x+2 using To = 0.5. Perform the computation until Eq is less than 0.01%. = Use fixed-point iteration to locate the root of f(x) = cos x - x² Use an initial guess of co 0.5 and iterate until a < 0.01%.
