The cosine function can be evaluated by the following infinite series:

the question in the picture

Please, explain as much as possible:)

The cosine function can be evaluated by the following infinite series: 4! 6! a) Write a MATLAB code to implement this formula so that it computes and prints the value of cos using 5 terms of approximation function above (1 term) cos(x) 1 cos(x) 1 (2 terms 2! x2, x4 cos(x) 1 (3 terms) and so on. Also, compute and display the percent relative error as true series approximation error X100% true b) What is the type of error resulted from this approximation (Name of the error c) Plot your solution for cos(x) in MATLAB and attach the plot
