Creative-ish things that can be graphed with sin/cos?

Doing a project in math where we graph an irl thing with sin/cos and I cant for the life of me pick something creative. Any ideas? (Algebra II student)

How to lose all unsaved progress permanently

here's what was copied to clipboard btw, idk why it copies stuff

I actually lost around 30-minutes of unsaved progress due to this D:

{"version":13,"randomSeed":"","graph":{"viewport":{"xmin":"-10","ymin":"-13.25","xmax":"10","ymax":"13.25"},"__viewportEvaluatedForBackMigration":{"xmin":-10,"ymin":-13.25,"xmax":10,"ymax":13.25}},"expressions":{"list":[{"id":"1","type":"text","text":"https://www.desmos.com/calculator/qhjzbkdfqr?simulationFPS"},{"id":"2","type":"table","columns":\[\]}\]}}

Theta made using only theta! (and one r) (remake)

One of my first posts to the subreddit was theta made with no letters or numbers but theta, however it was very badly executed and I have been wanting to remake it for a while. Finally got around to it :3, down from 19,342 to 1,514 theta symbols, along with being exactly precise and overall way cleaner.

Game of Life - Optimized with Clusters

2x2 Clusters Link: https://www.desmos.com/calculator/b8vwyvwlp7

3x3 Clusters Link: https://www.desmos.com/calculator/a51wcew4h3

original reddit post: Conway's Game of Life (boundless) : r/desmos

I've been playing around with a method of optimization for Conway's Game of Life. It works by grouping a cluster of cells into a single numerical value. For a group of 2x2, it groups 4 cells into a binary number (up to 15). For a group of 3x3, it groups 9 cells into a binary number (up to 511).

This binary numerical value can be broken down into its individual bits, and by using those bits we can determine which cells are alive/dead within that cluster.

I've considered making a graph which uses 4x4 clusters, but I'm honestly not sure if there would be any noticeable improvement in performance. Going from 2x2 to 3x3 wasn't as big of a jump in performance as was going from 1x1 to 2x2.

Gerstner Waves in 3D

https://www.desmos.com/3d/dhtquctsac

Took some doing, and doesn't exactly run too well at higher resolutions. However I think it turned out really well.

The foam I did by running a 2nd derivative estimation on the z position of the transformed mesh points.

I think the boat is probably my favorite part of this whole graph tbh.

Having problems joining lists

I have two lists of points (L1 and L2) of length n and I want to combine them into a new list (L) such that they alternate the points from L1 and L2. Example below:

L[1]=L1[1]

L[2]=L2[1]

L[3]=L1[2]

L[4]=L2[2]

...

and so on

Lists L1 and L2 change length(number of points in list) with a slider n. So my question is how do I have make a function that automatically combines them in this way, for any(reasonable) value of n? I've looked at the for statement and recursive functions and summation but can't find any simple answer. Am I overlooking a simple answer or is this just not an easily accomplished task? Would appreciate even just being pointed in a direction or being told this is or isn't possible. Thanks!

3D diffraction of light through a water droplet

I made a 3D interactive graph of the process that creates rainbows following the one I previously made in 2D (which I realized contained a mistake). This took days to make and I almost gave up 5 times. Who knew this could be so difficult? I made it as accurate and user friendly as possible. I might later implement more accurate diminishing of the light’s intensity when I have time.

How to compress xeno's curve

I'm trying to compress xeno's curve to start at 0,1 and end at 1,0

Formula I'm using for xeno's curve

Y=(1/(x^2))

Edit: I think I type the wrong formula I meant y = 1/x

bro. why when i put random(V) in the graph manually in the p(n) function equation, it plots the sierpinski triangle but when I multiply a by c where c is random(V) or a draggable point, it doesn't plot the sierpinski triangle??? its supposed to be the same.

also sorry for bad wording. i think you'll get the idea of what i want it to behave by the video.

Somewhat functional portals in Desmos (Work in Progress)

A simple project that "teleports" whatever part of the graphed function (black) is under the blue portal directly to the orange. Currently only works for f(x)=x and doesn't support recursion (portals on top of portals, one is basically physically under the other) I'd like your opinions thus far! https://www.desmos.com/calculator/mygwiwytzh
