[Blindmath] List of Common Unit Circle Trig Values

[Lloyd Rasmussen]

You could write a program in any number of languages to calculate these 
values and output them to a file of your own design.  Or you could set up 
an Excel spreadsheet which you could, optionally, save as an HTML 
table.  This sounds like some of the technical braille tables which 
Dr.  Tom Benham, W3DD, distributed to some of us more than 40 years ago.
