Hey everyone, I have some problems here involving the comparision test and Alternating series tests for series. I've solved most but there are about five i'm lost on. All I'm asking for is a couple hints. Thanks Theres only one alternating series question so I'll put that first.(adsbygoogle = window.adsbygoogle || []).push({});

AST:

[tex]\sum^{\infty}_{n=1} (-1)^nsin(\pi/n) [/tex]

Comparison or Limit Comparison:

[tex]\sum^{\infty}_{n=2} \frac{n^2+1}{n^3-1}[/tex]

[tex]\sum^{\infty}_{n=1} \frac{1}{n!} [/tex]

[tex] \sum^{infty}_{n=1} \sin(\frac{1}{n}) [/tex]

OK and this last one :

[tex]\sum^{\infty}_{n=1} \frac{5+2n}{(1+n^2)^2}[/tex]

I know I dont have any work but I'm stuck on these five. All I'm asking for is a couple hints thanks in advance.
