Consider the power series. E (-1)"I 6" (722 + 11) The interval of convergence goes from to z The radius of convergence is R = If needed. enter INF for co and -INF for -- co Note: You can earn partial credit on this problemDetermine the sum of the following seriesn +8 Use the ratio test to determine whether converges or diverges n! 26 (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For n > 26 lim lim (b) Evaluate the limit in the previous part. Enter oo as infinity and -oo as anfinity. If the limit does not exist, enter DNE lim (c) By the ratio test. does the series converge. diverge, or is the test incon
