[Blindmath] Unit Circle

[Brad and Jill Weatherd]

Hi Justin and others,
Thanks so much for responding so quickly!  She just needs either a Brailled
and raised line unit circle showing the 4 quadrants, the angles, the
degrees, and radians or even a table that includes that information would be
great.  I'm thinking I could make some kind of a table, but I'm pretty
math-impaired so that might not be such a good idea.  Got any ideas?  Thanks
again, Jill

Hi Joel,

    I am a mathematics major and am very familiar with said unit circle.
The equation x^2 + y^2 = 1 is the correct equation for it.  Are you looking
for an accessible version of one such as a raised-line drawing of a unit
circle, or were you merely looking for the information on what the unit
circle is?

Good luck!

Justin

This might help explain what he's looking for.

  The only unit circles I know are any circle whose radius is 1 or else the
circle whose center is at the origin (0,0) and has equation
x^2 + y^2 = 1.
