solving trigonometric equations doesn't show all solutions

I'm trying to solve a very simple trigonometric equation but for some reason Maple shows me only a single solution where there are more than one.

For example in this code:

restart;

f:=sin(x);

solve(f,x);

Maple returns x=0. eventhough there's another solution x=180 (or pi).

Anyone knows how to force Maple to return all the solutions?

Thanks
