23. Use MATLAB to show that the sum of the infinite series to 6. Do this by computing the sum for

(a) n=5,

(b) n=15,

(c) n=30 converges For each part, create a vector n in which the first element is 1, the increment is 1 and the last term is 5, 15, or 30. Then use element-by-element calcula- tions to create a vector in which the elements are Finally, use MAT- LAB's built-in function sum to sum the series. Use format long to display the numbers.
