Consider the following convergent series. Complete parts a through d below. 7 5k4 K = 1 c. Use an integral to find lower and upper bounds (L, and U respectively) on the exact value of the series. Ln = Sn + and Un = Sn + (Type expressions using n as the variable.) d. Find an interval in which the value of the series must lie if you approximate it using ten terms of the series. Using ten terms of the series, the value lies in the interval (Do not round until the final answer. Then round to nine decimal places as needed. Use the answer from part c to answer this part.)
