Talk:Nth Root Test

Why $\limsup$ and not $\lim$? --GFauxPas 08:49, 17 February 2012 (EST)


 * To cover common cases where the sequence is bounded but does not converge. For example when all the even terms are zero. Limsup then still makes sense, while lim doesn't. --Lord_Farin 09:25, 17 February 2012 (EST)


 * Got it, thanks --GFauxPas 09:38, 17 February 2012 (EST)
