1 "4 4. For the series Z[()T00] , do the following: n-l n I a. Calculate the sum of the first 4 terms, S4. b. Find a bound for the error of S4. Be sure to check the series is convergent or divergent first. c. Calculate the number of terms, n that must be added in order to find the sum so the error is less than 16
