Consider the following sum: S = 0.5 + x2x1+1 x2x2+1 (2 x 1)! (2 x 2)! ++ ***** x/+1 (2j)! x2n+1 (2n)! Write a MATLAB code that does the following: 1- For n-50 and for 20 values of x from 0 to 2n compute and display the sum S. Hint: You need a nested for loop 2- Make a plot of x versus S with appropriate labels.
