Hey guys, I have some infinite series problems I need my solutions checked to.
Problem 1. Use the ratio test to determine whether the series converges or diverges. Explain how the test permits you to draw your conclusion.
My Solution
Since
, the ratio test fails.
Here, I have trouble thinking my solution is right because the directions make no mention of the test failing. Is my solution correct?
For problems 2 and 3 determine whether the series converges absolutely, converges conditionally, or diverges. Explain how you drew your conclusion in each case.
Problem 2. Problem 3.
I don't know how to do either of these problems, help please!
Thanks in advance for all help!
