Question

The measure of angle θ is 600°. The point (x, y) corresponding to θ on the unit circle is? (___,___) the options for inside parenthesis are A.) -(3^(1/2))/2 B.)-1(2^(1/2))/2 C.)-1/2 D.) (3^(1/2))/2

Answer 1

600 = 360 + 240

In unit circle, (x,y) = (cos(240), sin(240) ) = (-sqrt(3) / 2, -1/2)
