Question 5 (8 marks) Consider using the Fibonacci method to search for the value of x at which the function f(x) = x sinx + cos x, 45x 56 is maximised. How many iterations are needed to determine the value of x with an absolute error less than 0.3? Determine the value of x. Write your answer correct to 3 decimal places.
