I understand the first part:

Lim x->0 (cos(3x)/sin(3x))/(1/sinx)

which reduces to:

Lim x -> 0 (cos(3x)sin(x))/sin(3x)

but I'm at a loss of where to go from here. Everything I try either becomes so complicated I don't know what to do with it or ends up as 0/0. Thanks in advance to anyone who can shed some light on this dilemma.
