4( – 1)*+1 A k(k + 4) By the alternating series test, the series converges. Find its sum. 4 First find the partial fraction decomposition of k(k + 4) 4 k(k + 4) Then find the limit of the partial sums. * 4( – 1)*+1 k(k + 4) k=1 Enter your answer for the sum as a reduced fraction.

Q: Find the sum of the series: (- 1)"4" 3 (2n + 1)!

A: We know sin x = ∑n=0∞(-1)n x2n+1(2n+1)! Putting x=2, we get sin 2 = ∑n=0∞(-1)n 22n+1(2n+1)!
