Use MATLAB to show that the sum of the infinite series converges to e2. Do this by computing the sum for:
(a) n = 5,
(b) n = 10,
(c) n = 50
For each part create a vector n in which the first element is 0, the increment is 1 and the last term is 5, 10, or 50. Then use element-by-element calculations to create a vector in which the elements are 2n/n!. Finally, use MATLAB's built-in function sum to sum the series. Compare the values to e2 (use format long to display the numbers).
