Webb22 juli 2024 · In the unit circle, the point at angle theta from the origin has a y value of sin theta. If you rotate a point 360-theta degrees from the origin, that is like rotating it theta degrees "backwards", or downwards, which is going to yield the same exact point, reflected through the x-axis.
