There are two angles in the unit circle, x=0 and x=, whose sine has a value of zero.

We get the full solution when we add multiples of 2,

x=0+2nandx=+2n

where n is an arbitrary integer.

Note: Because the difference between 0 and is a half turn, the solutions are repeated every half turn and they can be summarized in one expression,

x=0+n

where n is an arbitrary integer.
