3. Use MATLAB to show that the sum of the infinite series converges to n-0 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 2n create a vector in which the elements are. Finally, use MATLAB's built-in function sum to sum the series. Compare the values to e2 (use format long to display the numbers)
