Hi, We put a list of resources for end users asking questions about Sage for the cocalc docs here: https://doc.cocalc.com/howto/sage-question.html?highlight=ask%20sagemath%20org Are we missing anything important? If so, let me know or click the "Edit in Github" button... William -- William (

Re: [sage-support] Viewers in cocalc?

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,

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

[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
