Question

The measure of angle θ is 600°. The point (x, y) corresponding to θ on the unit circle is (

Answer 1

On the unit circle the hypotenuse is always one so we can say:

sinα=y/1 and cosα=x/1 so

The point corresponding the the angle 600° is:

(cos600, sin600) which is approximately

(-1/2, -√(3/4)
