Trigonometry With Tau as Circle Constant is a derived work, based upon Corral, M. (2013). Trigonometry, implemented under the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. Trigonometry With Tau as Circle Constant is written in the mathematical typesetting language LaTex, and you'll need a complete LaTex distribution on your computer in order to compile. As LaTex installations vary, I can't provide specific instructions for each computer/LaTex set up, but here is a suggested sequence to get started:
  1. Download and extract the archived file: either trigonometry_with_tau.tar.gz or
  2. In the directory, you'll find a file entitled ""; run this file from the command line (Unix, MacOS).
