The cosine function can be evaluated by the following infinite series: cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + Write a MATLAB code to implement this formula so that it computes and prints the value of cos(pi/3) using 5 terms of approximation function above. where cos(x) =1 (1 term) cos(x) = 1 - x^2/2! cos(x) = 1 - x^2/2! + x^4/4! and so on. Also, compute and display the percent relative error % error = true - series approximation/true times 100% What is the type of error resulted from this approximation (Name of the error). Plot your solution for cos(x) in MATLAB and attach the plot
