cannot calculate limit
No answer from Sage-6.4.1 for this limit :
var('n'); u = (1+sqrt(n))^(-n); limit(u(n=n+1)/u,n=infinity)
Sage 4.7 gives 0 (correct). Why ?
Thanks ! Note that converting to exponentials works. My best interval is (4.7, 5.8), sorry
This does not evaluate (returns the question) in 5.2. So it's been a while. Thierry, maybe you can isolate the Maxima command and report upstream?
I never used maxima commands (nor maxima itself), but if you give me some hints me how to do that, i will be glad to.work on it.
The maxima command is: limit((1+sqrt(n+1))^(-n-1)/(1+sqrt(n))^(-n),n,inf)
Returns zero with Maxima 5.24.0 and is not evaluated when running in http://sagecell.sagemath.org/
Thanks @robert.marik - I reported this upstream at https://sourceforge.net/p/maxima/bugs...
This is now http://trac.sagemath.org/ticket/17709
