I've almost done my latest assignment, but for a couple questions of which I'm hopelessly stuck at. I'm not sure how to proceed with them.
If anyone could give me advice on how to get started on them, I'll be a very happy crustacean.
where p>0 & a>1
2. Test for convergence/divergence:
what test do I use here? Integral? If yes, what should I make u=?
3. For what values of k isthe following series absolutely convergent? For what values k>=0 conditionally convergent?
where do I even begin here?! I hate logs!
for all n, and
Show that the power series:
has a radius of convergence
This is what I did:
Use Ratio test:
since we know
Is this the correct way to prove this? I ask because it just seems too easy. I'm always of the opinion that if I find it easy it's likely because I've done something wrong!
Thanks for any and all help.
