1. (Alternating Series Test.) This shows that for this particular sort of alternating series, the error in approximating the infinite sum by a partial sum is at most the first omitted term. Suppose that aj > a2 > a3 > ... > 0 and that limnyoo An = 0. Let sn = {k=1(-1)kak. (a) Prove that if n > m > 0 then |sn – Sm! < am+1. (b) Prove that 2-1(-1)kak converges and that, for all n > 0,...
Study: Ch. 5 5.2 #93-96, 5.5 280-285 The given series converges by Alternating Series Test. Use the estimate |RN| <bn+1 to find the least value of N that guarantees that the sum Sy differs from the infinite sum n n=1 by at most an error of 0.01. Answer (a) What is N? (b) What is Sy and what is the actual sum S of the series? (c) Is S - SN <0.01?
I need help on proving problem b. (-1)"+1a, be an alternat- Theorem 7–16 (Alternating Series Test): Let ing series such that (i) anan+1 > O for every n. (ii) lima, = 0. Then (-1)*+la, and (-1)"a, converge. (b) Let [(-1)"+1 an be an alternating series satisfying the hypotheses of Theorem 7–16 and converging to L. If {Sn} is the sequence of partial sums associated with the series, then |L-S <|an+1l.
Find a formula for the nth partial sum of the series and use it to determine if the series converges or diverges. If the series converges, find its sum. 10 Σ 10 n+1 n n=1 Sn If the series converges, what is its sum? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The series sum is (Type an integer or a fraction.) B. The series diverges.
