well...
the bottom obviously goes to ∞ when x->∞
and as for the top.. I have no idea...
that's where i got stuck the 1st time..
what do you do with cosx when x->∞?
the graph is attached
ok.. I think I see where u're going with this...
so it's actually not defined when x->∞
The case for x->0 is much easier - the answer is 1/4...
is that what u meant?
Thanx!
I drew the graph, it seems to be going to zero when x->∞
and unfortunetally it is x->∞ and not x->0
but I'm a bit stuck with the limit...
any ideas on how to approach it (analytically)?

hey guys, can anyone please help me solve this limit (without a calculator..)
