Find the coordinate of the point (x, y) shown on the unit circle

Here the angle is

And radius is 1 units .

And

Substituting the values of theta and r, we will get

So we will get

The coordinate of the point (x,y) shown on the unit circle is therefore: (-1/2, -√3/2)

The circle given is a unit circle.

In essence, the radius as indicated by the blue line is 1.

The angle subtended by the line is; 4π/3.

Therefore, from trigonometry of right-angled triangles; we have;

where, r = 1

Therefore,
