Alternating Series - Another Example 1

@Abigail Jimenez if you can't see that n/n^3+1 is going to 0, then just further simplify that fraction. You can cancel n on the top to get 1/n^2+1 which is much easier to visualize that the limit of that fraction is going to 0 as n approaches infinity.

thanks for the variety of examples. It really helped.

Thank you! you make me love math again! :)

But what if I get task to test apsolute emergence, conditionally convergence or divergence? What to do

[manolo]

what would you do if 1). it goes to zero but 2.) it is NOT decreasing??

[abigailjimenez]

when you took the limit of the problem isn't infinity over infinity indeterminate. How did you get zero?
