Newton's Method requires applying the recursion formula: 2n+1= n f'(xn) a) Consider the function f(x) = x²1.8. Show that a root exists in the interval [1,2]. b) Using two iterations of Newton's formula above evaluate √1.8, making use of the function f(x) = x² - 1.8 and assume an initial guess is 20 = 1. Compare your answer with the "true" result from a calculator.
