a point on the unit circle is (1/2,3squared/2). what is the sine of the angle formed by a terminal ray that intersects the unit circle at this point?
-3squared/2
1/2
-1/2
3squared/2
To find the sine of the angle formed by the terminal ray, we need to find the y-coordinate of the point on the unit circle, which is given by (1/2, 3^(2)/2).
Since the y-coordinate is 3^(2)/2, the sine of the angle formed by the terminal ray is 3^(2)/2.
Therefore, the correct answer is 3^(2)/2.
