@AlexSilva No. I made an edit to make it clearer.

@Student T Thanks. If you could give me a link or two to the "tons of material online" I'd appreciate it. My own googling has turned up little (beyond wikipedia).

comment Can the $9$ point circle be generalized to $n$-gons of $n\gt3$?
Yes, but the vertices of your pentagon are not concyclic.

comment Looking for a nice expression of these functions in terms of trig functions
Thanks for this. Yes, I like the idea of plotting $f$ straight from the curves. I actually know what the critical points are. The minima are at 110 (i.e. $11/36 \pi$) and 180 degrees, for example. So I need a function which can satisfy $f(11/36 \pi)=f(\pi)$.
