that time i made ENA in the desmos graphing calculator

i had this idea while watching dead poet society that Robert Sean Leonard is so angular he could be drawn in the Desmos graphic calculator

Making rnd in desmos :D update 1

Heads are done :3

bro why do i have to be such a try hard

like i'm literally telling myself that ending with a B in an online college class that crams everything into one semester as a high school student whilst juggling other activities and honors classes is still impressive

but my try hard ass keeps getting all disappointed

like girl you can get your GPA back up when you start classes next year its fine

(i'm doing dual enrollment so the college classes i take should hopefully give me a boost back up to a 3.4 or so)

Graphing Calculators are the same breed as printers and are actually more evil

Desmos Marble Slides Challenge

So I recently came across a fun little trend where you play this game with desmos. The way the game goes is there's a position that drops several marbles with slightly randomized velocity and collect a number of stars, as the marbles bounce along user defined functions.

Well anyways, I started playing around with a lesson plan designed for teaching linear equations, and of course breezed through the early lessons. At some point I thought to myself, well i can do some of these multi-line problems with one equations if i dont use linear functions. So here's what some of those look like

That one was pretty simple. A little finicky and rng dependent because sometimes they all bounce to one side, hence the sliding the function over by 0.01 to get them more centered. Here's a more fun one you can create with a tweaked 1/x to build momentum, summed with a linear equation to form an asymptote, then limited by restricting the x input to create a bit of a ramp

I used a similar trick earlier in this problem right here

One problem however gave me significant trouble to try to one-line, and that would be this problem here

I tried multiple things. I tried mirrored, cut circles that formed a pair of half pipes (hitting the sharp edge killed too much momentum for the marbles to go anywhere), I tried vertical sine wave variations with holes cut in them to filter marbles back and forth. I tried creating an upside parabola with a weird elliptic curve cutting into the vertex to get marbles to wobble from side to side. None of it worked. That is, until I had a genius solution.

When in doubt, turn it into a pachinko game c: used some modular arithmetic and domain repetition I borrowed from raymarching

And thus, this beauty was formed c:

I made a game I call yellow. Here's how to play:

press the play button next to b.

when you see the color yellow, press pause.

the value of b is your score!
