Problem 3: Life is better when there are options. The series can be analyzed in many п(п - 1) n=3 different ways. You will discover them below! (a) Show this series a telescoping series. (You may need to find a function f(x) so that Sp = f(n), where {Sm} is the associated sequence of partial sums, see the hint in the next part.) Find the sum of this telescoping series. (b) Use the Integral Test to determine whether the series converges or diverges. What is the value of the associated improper integral? Be sure to carefully write out your argument. (Hint: write out the telescoping series in the form E3 A - for some constants A, B and apply the integral test to this series.) (c) Does the sum of the series in part (a) match the value of the improper integral from part (b)? Should it? Briefly explain the reasoning that allowed you to make your conclusion.
