You can put this solution on YOUR website! Find the exact value of the point on the unit circle intersected by an angle of 240 degrees.
The reference angle at 240 deg is 60 deg.
This is in the third quadrant of a unit circle where the sine and cos values are negative. In the unit circle, x=cos60=-1/2, and y=sin 60=-sqrt(3)/2
ans: the point on the unit circle intersected by an angle of 240 deg is (-1/2,-sqrt(3)/2)
