It can be computed as 2/(sin(alpha))^2 where alpha is the pressure angle. By default, the gear modules produce corrected gears. You can override this by specifying the profile shift yourself. A small ...

The Sine and Cosine rules can be applied to find any unknown side or ... The ambiguous case of the Sine Rule occurs when there are two possible solutions for the same information. An example is drawn ...

This algorithm has quadratic run time so it can be slow with large profiles. The "tangent" method generally produces good results when connecting a discrete polygon to a convex, finely sampled curve.
