f=(e^(-x))/(2+ sin(x));
limit(f,x=infinity)

this yields "undefined", but the limits is clearly zero, thus I gather there's a bug or I am missing something basic . All help is appreciated.

If Maxima is unsatisfactory, try SymPy:

sage: f = exp(-x) / (2 + sin(x))
sage: import sympy
sage: sympy.limit(f,x,oo)
0

Yes it is a bug. And still present in the development version sage-6.6.beta2. I opened ticket #17878 for that. Thanks for the report! I hope it will be fixed in a next release.

It certainly looks like a bug. Limit is 0 - WolframAlpha gives limit as 0
