Forum Discussion question.

(a) Determine the root of the function f(x) =x^2 - cos x using 4 iterations of the regula falsi method. Show the steps in your method clearly.
(b) Determine the root of the function  f(x) =x^2 - cos x using 4 iterations of the secant method. Explain your method clearly.
(c) What is the accuracy of your answer in 2 (a)?
(d) What are the similarities and the differences between the secant and the regula falsi method? Which method would you prefer and why?
