A more interesting question is: should the limit(cos(x)) as x-> infinity
should be defined as an interval [-1,1] ?

which is sort of what I got from Maple and Mathematica.
Or undefined. Or indefinite.
Actually the meaning of "infinity" is ambiguous -- which direction?
All? Any? positive real infinity.
