24. The natural exponential function can be expressed by e (a) n = 5, (b) n = 15, (c) n = 25 = Determine e by calculating the sum of the series for: n! n=0 For each part create a vector n in which the first element is 0, the increment is 1, and the last term is 5, 15, or 25. Then use element-by-element calculations to create a vector in which the elements are Finally, use the MATLAB built-in function n! sum to add the terms of the series. Compare the values obtained in parts (a), (b), and (c) with the value of e calculated by MATLAB.
