[Blindmath] List of Common Unit Circle Trig Values

[Jared Wright]

I for months have been living and dying by this fantastic Braille 
cheatsheet that outlined all the important values of the trig functions 
along the unit circle. All six trig functions for \frac{\pi}{2}, 
\frac{pi}{4}, \frac{7\pi}{6}, etc. Basically every angle in intervals of 
\frac{pi}{12} up through 2\pi, covering the entire circle in a very 
Braille-friendly table. Then I went and lost it. So before I make up 
another by hand, does anyone know where something like this in tabular 
form is, in LaTeX or some other accessible medium? Everything I can find 
is of course superimposed onto a circle, which isn't really the most 
intuitive way for speech and its serial mode of communication to get 
things through. Thanks for any suggestions.

All the best,
JW
