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 ?

I do not know exactly why, probably a regression in maxima
. If you really want to know, you should provide a smaller interval of versions than (4.7, 6.4.1) so that we can have a look at the guilty commit. That said, you can still ask sympy
to do that:
sage: limit(u(n=n+1)/u,n=infinity, algorithm="sympy")
0
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...

How do I understand the result of symbolic integrals
Plotting an integral with a variable as a limit
Limit computation causes Sage to crash
sage cannot get the simplest form on the limit expression with binomial and exponential operations
Is this a bug or what am I missing, simple limit computation
Sample question: How do I compute symbolic integrals like $\int{sin(x) tan(x)} dx$
why is symbolic comparison so slow?
This is now http://trac.sagemath.org/ticket/17709
