I have been dabbling with the idea of presenting trigonometric formulas through a unit circle representation on GeoGebra. However, I cannot seem to figure out a way to not have the angle be a slider, but instead something that appears from moving a point along the circle.
To be clear, the app should consist of a unit circle and a point on a circle that the user can manipulate to see the resulting angle, and thus its sine, cosine, tangent, etc. I am sure there is a way to do this, but I don't see it anywhere.

- I understand this lets you slide around the point, but I don't see how it determines an angle. I must be missing something easy. – Saegusa Commented Mar 15 at 7:50
