Good question. What sort of use are you thinking about for spherical coordinates? One idea that I can think of would be specifying a surface R(theta, phi). When I've needed...

> What these two things have in common: they involve partial derivatives. I've tried using diff with functions of multiple variables, but I just can't find a way to work...

Note to self: This is implemented but still needs documented examples.

I looked into this a little bit today. This seems to be an issue with color maps not refreshing when axis range is changed. To reproduce: 1. Create a surface...

>Edit: I've now realized that it can be easily done with a parametric surface, with [u, f(u,v), v]. Still, I think it would be nice to be able to switch....

I agree—a "saved graphs" tab would be great. This would require a user login system, which math3d doesn't have right now. (And would be a significant task that I don't...

@o-b-o If you haven't found it yet, there are static labels. See https://www.math3d.org/labels They're not dynamic, so you can't show the coordinates of a slider, etc, nor does it support...

Math3d actually already supports implicit multiplication of variables, but a space is needed. So `xy` is a variable, but `x y` is equivalent to `x*y`. This is similar to Mathematica's...

I have thought about it a little bit but do not have any plans to implement that soon. I think that "most" of what would be required is updating MathBox...
