The circle could've been done in one equation

[–] Ashelyn@lemmy.blahaj.zone 37 points 9 months ago (1 children)

One equation, sure, but not in one valid function (without making it parametric anyways)

[–] NorthWestWind@lemmy.world 4 points 9 months ago (3 children)

x^2^+y^2^=1
or, in this case
(x-2)^2^+(y-2)^2^=1

[–] SkybreakerEngineer@lemmy.world 19 points 9 months ago

Not valid functions

[–] NorthWestWind@lemmy.world 2 points 9 months ago

Ok you're right

[–] bob_lemon@feddit.de 3 points 9 months ago

A that's a single equation alright. But as the previous poster pointed out, it's not a function.

One time I was bored translated this formula to work on a TI-83 calculator

The original does work or course but it doesn't look right since the TI-83 isn't as precise as something like Desmos. You have to change the numbers around a bit to make it look right

[–] yimby@lemmy.ca 15 points 9 months ago* (last edited 9 months ago) (1 children)

It's the last equation j(x) that's wrong. What's plotted on the right is something like 0.2x+1.6

Your graphing calculator is more than capable of plotting linear functions just as well as desmos.

[–] JusticeForPorygon@lemmy.world 7 points 9 months ago (2 children)

I wasn't following the image, I was following Desmos's official formula.

The equation works, but since you can't zoom in on TI-83 (or at least I'm not aware you can) you have to scale up the formula to make the symbol appear properly.

i don't mean to be condescending but the TI-83/84 literally has a button labeled ZOOM

[–] JusticeForPorygon@lemmy.world 8 points 9 months ago (1 children)

Does it really? Man I felt so accomplished when I figured out how to make that formula work. Could've just zoomed in.

[–] tb_@lemmy.world 2 points 9 months ago

Regardless it was a good exercise to mess around with the formulas and see what happens, you're the real winner for having developed a better understanding!

[–] mkwarman@lemmy.mkwarman.com 4 points 9 months ago

You can zoom on the TI-83/TI-84 by either using the zoom functions or by setting the desired viewport size

Here's a video of someone doing it: https://youtu.be/tEkdCEhSZrY?si=ejhNefLX0qmOUofu

There’s probably a better set of equations out there, but that wouldn’t be as easy to just rip from Mastodon and post here. 🙃

[–] JusticeForPorygon@lemmy.world 13 points 9 months ago

Actually, if you just Google "Anarchy Equation" Desmos has a pre-loaded page with the equation graphed out.

If the police catch you spray painting math on the wall you are getting a wedgie and chucked in a bin.

[–] ImplyingImplications@lemmy.ca 8 points 9 months ago (1 children)

It's like when the police catch you spray painting poor grammar. Romanes eunt domus

[–] Fizz@lemmy.nz 2 points 9 months ago

Perfect clip 🤣

[–] jaybone@lemmy.world 8 points 9 months ago (1 children)

They’ll charge you with possession of math.

[–] Klear@sh.itjust.works 1 points 9 months ago

Jesse we need to calculate!

Peanut-sized brain cops? No surprise here, move along.

Fo the belt!

That's the anarchy symbol, not the Avengers logo. Fitting, considering it's spray-painted on a public structure.

[–] PastyWaterSnake@lemmy.world 19 points 9 months ago* (last edited 9 months ago) (1 children)

That's not the Anarchy symbol. That's the button disable "Auto Start-Stop" in Ford & Dodge vehicles

[–] danielf@aussie.zone 1 points 9 months ago

This guy gets it. Obviously the graffitist is making commentary on the darn radical leftists at Ford and Dodge, and how they want to "stop global warming" (like that's a thing, I'm very cold right now!) and "save people money."

Is this the maths homework of Banksy?
