The remainder estimate for the integral test. If the series converges by the integral test and , then Note that the remainder, , is the error made when the th partial sum, , is used to approximate the sum of a series, . PART 1. Use the 6th partial sum, , to approximate the sum of the series NOTE: enter an approximation accurate to 4 decimal places. PART 2. Estimate the error involved in using to approximate The size of the error is at most NOTE: enter an approximation accurate to 4 decimal places. PART 3. How many terms are needed to ensure that the sum is accurate to within
