Visual Bygrave, using cosine and tangent
From: Brad Morris
Date: 2009 Jun 15, 07:49 -0700

This version of the Visual Bygrave uses Cosine and Tangent curves.  
Interestingly, the solution angle is derived from the CoTangent.

Version 3 used Secant and Cotangent Curves, but the solution angle is derived from the Tangent.

Please note that I have been extra careful to use Bowditch style definitions 
of the trigonometric functions, which is 10+log(abs(trig function)).

This may lend some clarity to the discussion of what curves are represented on the Bygrave.

Best Regards
Brad
