Answer:

A.
((√(3) )/(2) ,(1)/(2) )

Explanation:

From the diagram produced, we require the coordinate of point P.

Applying trigonometric ratio in the right triangle.


sin \theta=(Opposite)/(Hypotenuse) \\sin (\pi /6)=(y)/(1)sin (\pi /6)=y\\y=(1)/(2)

Similarly


cos \theta=(Adjacent)/(Hypotenuse) \\sin (\pi /6)=(x)/(1)cos (\pi /6)=x\\x=(√(3))/(2)

The coordinates (x,y) of the point of intersection P are therefore
((√(3) )/(2) ,(1)/(2) )
