24. The natural exponential function can be expressed by e*= mine e by calculating the sum of the series for:

(a) n=5,

(b) n=15,

(c) n = 25 Deter- 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 calcula- " tions to create a vector in which the elements are Finally, use the MAT- LAB built-in function sum to add the terms of the series. Compare the values obtained in parts (a), (b), and

(c) with the value of calculated by MATLAB.
