DO k Consider the series E 15 + 4 k=1 (a) Use the Comparison Test to show that this series converges. (b) Write down a definite integral that represents an upperbound on the error incurred by ap- 10 k k proximating. by 15 + 4 15 + 4 k=1 k=1 (c) The integral in (b) is not one we have the tools to evaluate. But you can find an upperbound 1 on that integral, by comparing it to the integral of Evaluate this integral to find an upperbound on the error described in (b)
