Write a MATLAB function that computes cos ( (z-1)) in single and double precision using (1) for 48. The correct value is 0.707106781186548 Why are your results inaccurate? Why is the double precision result more accurate. Provide numerical evidence for your arguments. Based on this evidence find a way to compute cos ((x-1)) for x = 48 in single precision, accurately. Vhen you implement (1) you must consider the following: Since (1) is an infinite series, your algorithm theoretically should work forever. Stop when the sum of say the 50 first terms has been computed or if two consecutive partial sums agree to 5 significant digits. Do not use brute force in order to compute the individual terms of (1), find an efficient way to implement (1)
