real analysis - limit of nth root of factorial devided by n








I have a litle discution with a friend about the folowing limit:
limnnn!n


I would solve it like this: limnnn!nn=0

or
limnnnnn1n1n=111=0

and in this 2º way would there be a problem with 1? I would say that no, because there is no functions involved, since as much as I know this undetermination is because you would whant to avoid the situation such as f(x)g(x) where f(x)1 and g(x) Could anyone clarify this for me?

How to find limh0sin(ha)h without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
