This is a family of functions where a third variable sets the curve: It is a smooth function that approaches a sine curve when , and that approaches a hyperbola when .

It's a geometric function. It finds the tangent of a small circle on a sphere using trigonometry.

I'm asking if anyone else knows. Some of the online experts claim that this is just some set of trivial rotations. I'm wondering if anybody here knows for sure what this is. Has anyone seen it before?
