Question

Point A is on the following unit circle.

What are the coordinates of point A?
Enter an exact value or round to the nearest hundredth.

Answer 1

(x,y) = (0.5, 0.87)

Explanation:

lets say θ = pi/3

we have cos θ = x and sin θ = y

x = cos (pi/3) = 1/2

y = sin (pi/3) = sqrt(3) /2 = 0.87
