Fun question. There are a couple options:

(1) the more straightforward (but less powerful) option is to use the dynamic bounds for a slider. Here, "a" is set to animate, but the bounds don't let it move if b=0: https://www.desmos.com/calculator/mqhhpso67r

(2) the more general feature that allows for complex scripting behavior is called "actions." Here's an example that uses that, where it's more of a genuine play/pause: https://www.desmos.com/calculator/gzqwx36lo0

It's a beta feature that needs to be enabled, but anyone can turn it on. More here: https://help.desmos.com/hc/en-us/articles/4407725009165-Acti...

Nice! Really good to know. We'll add that to our list of device/browser combos that might cause trouble so that at minimum we can warn folks. It's an early beta so we're enthusiastically collecting any examples (system configurations and also graphs) that cause problems, so if you see anything amiss we'd love to hear about it ([email protected]).

Curious - do you have hardware acceleration disabled? Rotating the scene shouldn't be hammering the CPU if hardware acceleration is enabled. [disclaimer: I work at Desmos]

Despite knowing LaTeX, this is much more intuitive for me when communicating in plaintext. It just matches how I'd write it anyway. In an email I'd always use 1/2 or (f(x+h)-f(x))/h over their LaTeX alternatives.

If, however, the goal is to more easily edit LaTeX -- especially for folks who are less confident with LaTeX -- I suspect WYSIWYG is frequently a better option. MathQuill (mathquill.com), for example, is a fantastic open-source WISYWIG editor for LaTeX.

Disclosure: we use MathQuill heavily at desmos.com, where I work, and have contributed to its development.

Not natively (yet), but here's a 3D graph someone made: https://www.desmos.com/calculator/6uhmnazdo0

Yeah - I think it'd take some serious chops to construct this from scratch (note: it wasn't me! author: twitter.com/teachwithcode). But I've been having a blast deconstructing the equations.

Here's a fun intermediate step (circles instead of hearts), with a few of the numbers parametrized as sliders:
