plot functions with singularities. For example, when I enter the function SQRT(x*y),
and press the plot key, nothing happens. Is there something I an doing wrong?
I haven't tried this on the emulator yet.

Which version did you install? The polytrace version should handle singularities just fine. The two versions on the original first post do not handle singularities beyond stopping when they encounter them. If you are getting a blank plot, try entering and exiting the source code and make sure no errors are produced. Then try graphing again.

I installed Graph 3D v2.2polytrace (1-JAN-2014) and I used upper case X and Y
from the soft menu keys to enter the expression shift<x^2>X*Y. I press the
plot key and nothing happens-I just remain in the symbolic view. All other expressions
without singularities work fine. I will try this on the emulator and see if the problem
exists there.



EDIT: Also make sure your variables are all upper case if you don't already. As for SQRT(X*Y) -- SQRT() is a CAS function and does not always return a numerical value. You want the square root symbol [Shift][x^2].
