EDIT:
1) I decided to go with limit comparison test and got an answer so solved!
2) still unsolved
3) Used divergence test so solved!
4) Still unsolved
5) Still unsolved
I am having trouble with a couple of convergence/divergence tests for series. So far in class we've talked about the following:
- nth-term test
- geometric series test
- p-series test
- integral test
- comparison test
- ratio test
- root test
I've been working on harder problems but I am stuck. Could you point me towards the right direction and help me see the bigger picture?
Since the denominator grows faster than the numerator, then that implies that it diverges. According to Wolfram, the ratio and root test would be inconclusive but it would converge with the comparison test. So does it diverge or converge? What would I compare it to with the comparison test?
What do I do after that? According to Wolfram the it converges. Why is it equal ?
I have no idea how to even start this... Any suggestions?
How do I even begin to break that down so things start cancelling?
I have no idea how to begin this either!
I know I have a lot of questions but I would greatly appreciate any help you give me. I think I'm missing a key part. Thank you so much!
It is best to do a direct comparison here:
which is a p-series.
You must learn this basic fact:
Example: Because we know that
.
You will find yourself needing that kind of manipulation over and over again.
As for use the nth term test
