The series approximation of the cosine function cos(x) using n terms is given by: fcos(x) where Ck = n k=1 (-1)*-1 x2(k-1) 2(k-1)! n Ck k=1 {(-CK-1). for k = 1 ((-Ck-1) 2 (1-2) (21-3) for k>2 2k-2 (a) Write a MATLAB function file named fn_cos for computing fros(x) for 0 x 27. Make use of recur- rence calculations. (b) Make use of the function file fn_cos.m written in part (a) to draw the graphs of fos(x), fos(x), fcos(x), fos(x) and cos(x) for 0 x 2 in the same plot. Use proper legend to enhance the graphical display.
