this took me like almost 70 hours worth of brute forcing.

Probably some of my ugliest equations but oh well, made for mathemagicland's line only challenge

HELP!! Due to Desmos not letting you store lists in lists, I was not able to scalably plot all trails, so I only am doing one at a time. If anyone has an idea for how to scalably plot a trail for every single mass, please tell me!

I learned about Runge-Kutta recently, so of course I had to make this. It's really cool to see the emergent behavior of some of these systems just from a first-principles simulation.

There's a lot of buttons and such to operate it, but I think it's fairly intuitive. If anyone finds some interesting initial conditions, share a snapshot of the graph and post it here!

I don't know how useful this is but i made an approximate cosine wave like this for some reason, from testing, this is continuous (I'm pretty sure), the max absolute error is 0.020017 and max relative error is about 4.5%. i just find it funny how this possible

Anyone else have weird/cool looking graphs?

Many fractal / recursion graphs posted in this sub appear to paint in the "No Floats Exist Here" zones near 0 (closer than minFloat, but not at 0) and near ±infinity (further than maxFloat, but not at infinity). This seems like it should be impossible.

This notebook methodically lays out inequality and limit combinations for several graph types, adapted from those previously posted in r/Desmos.

For the most part, all you have to do is press buttons or move a slider, maybe wait a few seconds, and compare to the "what I got" results.

I would love to know how it's possible for inequalities to paint in these zones.

I know this has been done before but I'm new to Desmos and wanted to challenge myself, check it out :]

I'm still new to desmos! I can do lots of problems, but these proved to be a challenge. I'd be really grateful if somebody could point out my mistakes to me!

I have a student with extreme low vision. I have found reverse contrast and the bigger “A” option. But I haven’t found a way to make this keyboard bigger. Does anyone know how? Thank you!!!!

If you think the middle shape isn't weird, try moving one of the points around :P

I couldn't quite get the individual parts to rotate the right direction (which I imagine is a simple fix away) but the overall effect is still sorta there. https://www.desmos.com/calculator/xdktyomt9a

This Desmos notebook contains notes on the uniform distribution of random points on a 2-sphere.

it was fun but i never saw a proof because there has never been one or because i live under a rock probably, also would love to see this kind of challenge again some time, maybe even tougher u/mandelbrot4207

Block 10 shows the equation of the line. Block 11 shows the fluctuating length.

Made a whole Desmos notebook to solve this video: https://www.instagram.com/reel/DbzBtamsSSu/?exln=MjRmaDdsam0xcmkw

I made this almost two weeks ago, and it dawned on me that I could share it with you guys.
There might be some errors but this answer I got. And you can yell at me about the formatting all you want.

In my lecture today, I learnt about curvature (as a value).

Naturally, the very first thing I did was apply it to desmos. Another tool added to my collection. 😆

I hope it helps someone else, too!

they should make arctan() take 2d points next

Ok so I’m a smart lazy person and my teachers allow us to use desmos so I do the normal thing and make a calculator in desmos to do all my work for me( if you are interested I made a parabola solver based on if you have a single point and the vertex) but I want my friends to have their own calculators but each of them to be separate so how could I share them
