Re: Convergence of series

try the limit comparison test with the known convergent series $\displaystyle \sum \frac{1}{n^2}$

Re: Convergence of series

Hi

To use LaTeX put (TEX)(/TEX) tags around the text you want texified except that you shoul put [ instead of ( and ] instead of ) .

Re: Convergence of series

Thanks for the help. That's what I did, I just wasn't sure if it was right. Thank you!

When I put the tags around it comes up like this $\displaystyle \sum_{n=1}^\infty \frac{n+2}{n^3 +1}$

edit: it's working now! but I literally just copied and pasted form my original post! I'll try again.

Simple comparison works.

$\displaystyle \sum_{n=1}^\infty \frac{n+2}{n^3 +1}\le \sum_{n=1}^\infty \frac{2}{n^2 }$
