i do love it when i wade through a mass of online-only proprietary bullshit software to eventually find that there's a small foss library that does exactly what i want it to and a kde tool to view the output, we love happy endings

Some fun play, making my own @musicalsiphonophore style jellyfish! I like their tentacles better. Desmos

algebra 2 final notecard (featuring coinpin)

unfortunately getting tossed after the final so gotta preserve it while i can 💔

lil mistake—if the discriminant is < 0, it has two imaginary solutions! but if it asks for only real solutions, there are zero real solutions (note to self)

@ghostyghost202 i loved your coinpin doodles so much i was like, i gotta take this with me somehow. tysm your art is literally sacred to me

also asymptote reference? (those who know)

missed opportunity to put four and x on there i feel like they would love this. but i need coinpin to get through this final 🙏

thankfully it's. all multiple-choice

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:

heres some grids. because google wont stop giving me hydraulically compressed jpegs. the first one even has axis lines.

in my math class a while ago my friend (foolish)(inferior)(unfunny) made a bad joke (something to the effect of “coplaner? i barely know her”) and the teacher (sigma)(so old)(definitely knew what he was doing) made her explain it to him. this went on until she stood up and left

DUDE I was talking in a team in math and at some point I referred to a line as double prime and another teammate went "no, that's just prime, because it was rotated from the original line, not the translated one" and I was so confused cause then there'd be two primes??? And like there can't be line a, line a', and then another line a'. How would you know which one was which?? And as we kept trying to come up with solutions as to how to label these lines, something we didn't need to do in our work, we just kept talking ourselves into a circle, so eventually we called over our teacher and asked her what she would do. When we explained, we could like see her physically recoil and burst out into laughter, going, "Oh, oh, I don't know, that's scary! Oh, how would you do that?" Eventually, we decided on using subscripts, but it was so funny because it did not help us do our problem in any way, shape, or form

The smartest kids ask their teachers useless questions I guess lol

Hey hey! Little Rhody just broke Desmos! Feel free to try it yourself, equations are in the left of the image. (Don't quite get what that equation's supposed to represent -- I wish @desmos-calculator was here to explain it.)

Equations:

y=\frac{cx}{4x-5}

c=5

\frac{c\left(\frac{cx}{4x-5}\right)}{4\left(\frac{cx}{4x-5}\right)-5}=x
