Thanks!
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
is a commonly remembered trigonometric identity.
Substituting for in the equation given,
you get .
and are the x- and y-coordinates of the point
on the unit circle that you reach when you move along the circle counterclockwise
a distance from point .
The points with are on the diagonal bisecting quadrants I and III,
so there are only two angles with between and :
and .
