I'm standing in a circle (Point P), radius of 2000 with a center point 0/0. Then, I'm looking straight to the edge of the circle on a random point (B1 or B2) of the edge. How can I get the distance (f1 or f2) to the point when my rotation/angle is given?
Advanced: What happens if teta is not given, is it still possible to solve it?
My first tries: Depending on the angle, I'm using sin, cos, tan of my rotation * (the distance to the center point + radius). I tested some numbers and it looks like it's working. Does that makes sense and is there a better solution to solve my problem? It looks like I need several formulas depending on the angle teta and the Position P.
