[Blindmath] the unit circle

[David Engebretson Jr.]

Hi Dick,

Do you think a simple drawing of the unit circle could be drawn with your 
program?  Are symbols like the square root available?

For example, I can draw a plus sign as the x/y axis and have a circle with 
radius of 1 concentric with it, but can i label where the square root of 2 
is and have an arrow pointing to the lines created at the square root of 
two?

Thanks,
David
