Ratio test - Wikipedia, the free encyclopedia
Use the Ratio Test to determine whether converges or diverges.
(a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For ,
(b) Evaluate the limit in the previous part. Enter as infinity and as -infinity. If the limit does not exist, enter DNE.
=
(c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Choose Converges Diverges Inconclusive
So out of all my work all of this is correct except the denominator. I tried everything. When I put in (2n+2)! my online assignment says cancel out further and to simplify. WHAT???
I hate convergence/divergence. You all will soon learn that from my next several posts haha
Thank you to anyone that can help!
