A first attempt to rasterize arbitrary 2-D functions using the signs of four sample points (one for earch corner of a pixel). It works, but it can be optimized further by using a quadtree and recursively sample the sign values using that, instead of iterating over every pixel.

#desmos is out of control. Here is my guide to all of the features I've found so far. You can make logic gates in there. You can do lists and iterate things:

They've added summation and it's a little strange sometimes how it works. This threw me. You set i to be a list and it give you three answers. It won't evaluate it if you don't set an upper bound.

I'm excited but also a little horrified that this is the new SAT calculator. It's just so feature-rich.

Fun! Well-known online #math #visualization utility #desmos doesn't have a way to save gifs, but someone created one

Which let's me share this animation of a #satellite #orbit thing I'm trying to figure out

wait a minute...#mastodon doesn't support #svg??

and neither #imagemagick nor #ffmpeg support converting animations directly???

Ugh, I don't want to fight this battle today.
