The circle could've been done in one equation

[–] Ashelyn@lemmy.blahaj.zone 37 points 10 months ago (1 children)

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

[–] NorthWestWind@lemmy.world 4 points 10 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 10 months ago

Not valid functions

[–] NorthWestWind@lemmy.world 2 points 10 months ago

Ok you're right

[–] bob_lemon@feddit.de 3 points 10 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

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 10 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 10 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 10 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 10 months ago (1 children)

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 10 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 10 months ago (2 children)

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

[–] Fizz@lemmy.nz 2 points 10 months ago

Perfect clip 🤣

They’ll charge you with possession of math.

[–] Klear@sh.itjust.works 1 points 10 months ago

Jesse we need to calculate!

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

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

Is this the maths homework of Banksy?
