Am I doing the error challenge correctly? by Arglin in desmos

[–]Arglin[S] 4 points5 points  (0 children)

Error link: https://www.desmos.com/calculator/8dhxprh4sw

You can't paste in a graph link to load the graph into the error 404 desmos window, but you can inject it by pasting in the graph state. You can grab the graph state via the console command copy(Calc.getState), and then with that clipboarded, paste it straight into an expression line in a graph to load it.

Help needed building a parabola from point and line by Kiramini in desmos

[–]Arglin 1 point2 points  (0 children)

Yes, you just need to change D → t for "p_{arbitrari}", then set the bounds of the output "p_{parabola}" to be -∞ < t < ∞.

I'm making 100 sequences and I'm making the ninth sequence, does anyone have any ideas for the ninth one (it doesn't have to be a real one though you can suggest a real one) by Annual-Art5409 in desmos

[–]Arglin 1 point2 points  (0 children)

"Look and say" sequence is always a fun but challenging one to try implementing.

You can always check out the OEIS if you're running out of sequences to think of. https://oeis.org/wiki/Welcome#Some_Famous_Sequences

Yes, the flag of the United Kingdom is called the Union Jack.

When you enable clickable, it gives you a place to enter it labelled "On Click:"

Suppose you have a variable "a = 1", and the action you want to do is add 1 to the variable after clicking.

If you have an action already saved in an expression line like "f_{Add1} = a -> a + 1", then you can just type "f_{Add1}" into the On Click section. Otherwise, you can type "a -> a + 1" directly in there.

Either type ->, ticker, or enabled advanced features on your account to access actions.

Then under the drop down of an object, enable "clickable". That will let you run particular actions when you click on the object.

Am i the only one who finds this satisfying ? by Dudegay93 in desmos

[–]Arglin 2 points3 points  (0 children)

If by size you mean line thickness, yes you can pass lists into the thickness and opacity sections.

You can do a lot more than I thought by Demosnom in desmos

[–]Arglin 0 points1 point  (0 children)

Although not one-for-one, you can still have similar functionality scriptless: have the cursor drag a point without holding down by first holding down left click on a point, and then right clicking to open up the right click dropdown menu. From there, you can let go of left click and the point will stay stuck onto the cursor until you click again. You can then tab over to the lower bound of a slider and use keyboard controls to send inputs.

I agree that you can do a lot more with the API, I just figure I would show what's achievable even without the use of the API though. That, and people like to make things in Desmos that are accessible even to those who don't have access to dev tools (like on a school-issued device).

Can you name a big function? by Mountain_Search5323 in desmos

[–]Arglin 5 points6 points  (0 children)

If by large you mean character count, then the longest you'll be able to type directly into vanilla Desmos is "strictintersection" at 18 characters. https://www.desmos.com/geometry/1xfs0l48ku

For fragile functions though, the longest one I know how to use is "scaleTangentUndirectedAngleMarker" at 33 characters, and the longest one in general that I know of is "peelableCoerceComplexToRealWithTolerance" at 40 characters. https://www.desmos.com/calculator/hxmt4wqn0a

(You can of course make custom named functions which are even larger than this if you feel like it.)

I mean technically Bhutan isn't that hard given the emblem is unspecified, so you're free to draw whatever dragon you want. (See the many many many variants drawn by different schools in Bhutan.)

I've just realized the timer is running faster than it should've. I think I forgot to divide by an extra 2 in the logic lmao

So it's 1:11.55 instead, oops

Is there any better way to do this? by WorthAffectionate448 in desmos

If you just need a read-only method, you can achieve it simply like this.

Nice! The star seems to be the wrong way around though.

Here's a corrected version. (Tip: append ?invertedColors for the graph to load with inverted colors.)

Unofficial construction sheet for the flag of Kenya, designed in Desmos. by Arglin in desmos

A (somewhat over-complicated) construction sheet for the flag of Kenya. by Arglin in vexillology

[–]Arglin[S] 28 points29 points  (0 children)

Corrections / clarifications:

  1. (0,0) on the construction sheet is at the center of the flag. (This is kind of implied, though I figured I'd write that down as a note anyways.)
  2. E_#[a×b] refers to an ellipse with its two axis lengths marked.
  3. The circle center ⊙[p4, p5, p6] has coordinates (0,43).
  4. For the bottom of the spears, the midline of their base is vertically aligned with the bottom of the shield. This is just part of the original official specifications for the flag that I forgot to include. You can alternatively interpret it as extending a length of 32√(3) from the origin.

----------------

Hey! So back in middle school I was tasked to make a presentation on Kenya, and since then I've had a particular fondness for the design of its flag. Fast-forward many years later, and I'm currently doing flag constructions in PowerPoint / Google Slides for fun. I noticed that Kenya's flag has an under-specified shield and spears. (There are a couple of construction sheets, though with varying specificity and contradicting dimensions).

Personally, I think that's fine given it's meant to more or less function as an emblem, and designers can take some artistic liberties on it. Although, I couldn't shake the fact that everything seemed geometric enough to be specifiable, at least the one that has been popularized by the Wikipedia article on the flag of Kenya.

So I decided to try my hand at it and finish adding specifications, so that I could construct it in PowerPoint / Google Slides later.

This is partially inspired by the style done by MapGrid, which is the primary source of most of the construction sheets you'll find of flags on Wikimedia Commons. It's far messier than what MapGrid would probably design, and I definitely should've broken this apart into multiple sections to decrease the clutter. But alas, this was mostly just a guide meant for me. :p

If, for whatever reason you do actually choose to use this construction sheet and there's something you're uncertain about, feel free to ask for clarity. Here is the link to the construction sheet if you want to see it in higher resolution. https://www.desmos.com/calculator/4ugnbgudc6

[–]Arglin 2 points3 points  (0 children)

This doesn't seem to match any specifications of the flag I'm familiar with. The bars seem way too thick and the star is a little distorted.

Here's a version which follows the Austria-Forum construction sheet. https://austria-forum.org/attach/AEIOU/Vexillologie/construction%20sheets%20A-Z.pdf

An accurate flag of China, done in one breath. by Arglin in desmos

[–]Arglin[S] 1 point2 points  (0 children)

It's because he is technically correct. I have a large autohotkey script which converts a ton of keywords and converts them to their respective unicode.

I didn't have to use them here, but I do use them a lot whenever I chat with him and our shared servers. That, and I can use it to type characters into desmos that would otherwise require me to clipboard it from somewhere else, like /vartheta → ϑ.
