There are two places on the unit circle where the 
-coordinate of the point of intersection with the terminal ray of the angle is equal to 
, and two places where the -coordinate of the point of intersection with the terminal ray of the angle is equal to 
. These are the four elements of the solution set to your equation presuming that you are interested in the solution set over the interval
