[sage-support] polyhedron H-representation: variables determined by equations

2019-02-25 Thread Daniel Krenn
The H-representation consists of equations and inequalities and the equations seem to be in some canonical form. Is there a method that returns the non-free variables (or indices), i.e. that are the variables completely determined by the equations meaning once a value for the other variables is fix

[sage-support] Viewers in cocalc?

2019-02-25 Thread david.guichard
When I try to specify a viewer in a plot3d I get an error if I try anything other than "tachyon". Even viewer='threejs' throws an error, though I think the default viewer is threejs. What I'm really looking for is a viewer that lets me display an orthogonal projection instead of perspective. I k

It doesn't matter--anything that looks like plot3d(blah blah blah, viewer='xxx') where xxx is the name of a viewer, like threejs or jmol, which the documentation for sage still seems to indicate are valid. Again, anything that would let me do an orthogonal projection would be good. On Monday,
