convergence of series

[jmat]

Hello to all the community, excuse my language, I searched if there is any way to study the convergence of series by Cauchy methods, Raabe, d'Alembert .... our Nspire

thanks

Well, that's quite difficult because there are so many cases in which none of these criteria will work (starting with alternate series !).

But you can use your calc to calculate the limits that come with each of these criteria...

PS : Augustin Cauchy and Joseph Raabe (as well as Jean Le Rond d'Alembert) deserve their capital letters !

Thanks, I thought I would have something scheduled for the forum as I have seen for other models.
