It's German for "formula".
hello
okey, we have a circle with a tangent line.
We know the x coordinate of the tangent point. we know that the line starts at x=0 Y=0.
we know the Y coordinate of the circle center. and we know the diameter of the circle.
i want to know the angle of the line.
If you click on the picture in the first post you can see all the numbers on the drawing.
do someone have a solution for this or can point me in the right direction?
Regards
ML

I replaced your specific numbers with variables to try for a formula, and ended up with a fourth-degree equation in the cosine of the angle (or with a fourth-degree equation in any other unknown I tried. Probably the same will happen if you use your coordinate geometry approach.
I suspect there may not be a formula (that is, a reasonably simple formula) that you could use. Some sort of numerical method is likely needed.
