Restricting polar point to a particular angle

In the Cartesian grid, you can use the Point command to locate a point on a particular object.


I'd like to restrict a point in the polar grid to a particular theta, so the point slides along the line theta=pi/3, for example.


How can I do that? I can only seem to define the polar equation in terms of r...

Angle Slider α then

Point(y=tan(α)x)

Yes. For some reason, I was limiting my thinking to polar forms only in the polar coordinate grid. But Cartesian forms are valid there, too! Thanks! I also added restrictions (x>=0 or x<=0).
