## Approximate the sum of the series by using the first six terms. (Round your answers to four decimal places.) sigma_n=0^infinity (-1)^n 4/n! Approximate the sum of the series by using the first six terms. (See Example 4. Round your answer to four decimal places.) sigma_n=1^infinity (-1)^n + 1/4^n Use the Alternating Series Remainder Theorem to determine the smallest number of terms required to approximate the sum of the series with an error of less than 0.001. sigma_n=1^infinity (-1)^n + 1/n^6
