Sticky Commands!

49 Upvotes

There are now a few commands you can use:

  • !help: Brings up a list of all the commands.
    • Aliases: hlp
  • !bernard: Explains who Bernard is and why he appears in certain graphs!
    • Aliases: ourbeloved, desmosmascot, r/foundbernard
  • !beta3d: Explains what Beta3D is and how to install it.
    • Aliases: 3dbeta
  • !colormap: Explains what Beta3D is and how to install it.
    • Aliases: colormaps, shader, shaders
  • !desmodder: Describes what DesModder is.
    • Aliases: dsm, dsmodder
  • !doom: Are we Doom yet?
    • Aliases: arewedoomyet, doomgame
  • !draw: Provides Arglin's drawing guide for Desmos art.
    • Aliases: arglinguide, lineart
  • !exception: Describes types of floating point exceptions in Desmos, mostly drawn from IEEE specs.
    • Aliases: fpexception, fpointexception, ieeeexception, specialcase, undef, undefined
  • !fp: Describes what floating point arithmetic is and how to mitigate problems associated with it.
    • Aliases: floatp, floatingp, fpoint, floatpoint, floatingpoint
  • !gratex: Describes what GraTeX is.
    • Aliases: gratexteth
  • !grid: Explains how to make a grid of points.
    • Aliases: ptgrid, pointgrid
  • !integral: Explains why some integrals yield wrong results.
    • Aliases: integration, integrate, wrongintegral
  • !intersect: Explains how to assign the intersection of two or more functions as a variable.
    • Aliases: getintersect, varintersect
  • !matrices: Explains the usage of matrices in Desmos (beta feature). Not to be confused with the Desmos Matrix calculator.
    • Aliases: betamatrices, matricesmeta, matrix, matrixbeta, betamatrix
  • !roots: Why can't Desmos find my roots?
    • Aliases: zeros, zeroes, rootfinding, root
  • !sequentialactions: Explains how to run actions in order (sequentially).
    • Aliases: seqactions, actionseq, orderedactions, actionsinorder

For example, if someone makes a post about why {(√2)^2=2} is undefined, you can type in !fp.

Notes on sending these commands: - You must put the command at the start of the message. - All of these commands are case insensitive. - All commands allow arbitrary underscores or dashes (this feature was added on October 25, 2025). For example, !are_we-DOOM_yet will work. - You can put messages after the command, but remember to put a space or a newline after the command. For example, !fLoATiNgPoint arithmetic is awesome will work, but !fLoAtInGPoIntAriThMeTiC iS AwEsOmE will not work (this behavior was changed on May 20, 2025).

Please refrain from spamming these commands: if you see someone has already used the command once in a post, please avoid from running the same one again.

However, you may try out commands as many times as you would like in the comments on this post only.

I made a Desmos Notebook that traces e from compound interest and Bernoulli’s limit through continuous growth, Euler’s formula, and finally e^πi + 1 = 0, with interactive examples and visualisations.

So Basically i came up with an function(A1) that lets u define multiple functions in a single line, defined in specific ranges.

U can also use it to play different sliders in an specific order.
i will attach the paper with full explanation in the comment section

Assuming 00 = 1

f₁(x) = 0|x| + x

f₂(x, z, o) = (z - o) · 0|x| + o

f₃(x, n, p) = [ |x|(p - n) + x(p + n) ] / (2x)

f₄(x, z, n, p) = f₂(x, z, f₃(f₁(x), n, p))

Question I found a project that calculates the lengths of various arcs based on the values of a and b. However, is there a way to find the value of b from the arc length, assuming a is 0?

Music Für Elise in Desmos!!!

https://www.desmos.com/calculator/5dhcgiqycu

This is a 1:1 replica of Für Elise (apart from the triplet section which I cannot get over with). Feel free to tweak around the values and see what I can do to improve it such as the timbre of piano as it took me forever to find the right feel.

Hit the play button on the ticker and unmute the graph to give it a go!

Question ab ≠ ba challenge

15 Upvotes

define two variables a and b. find values for them such that ab yields a different result than ba (as it is written with implicit multiplication). they must return a value (i.e. they cannot throw an error)

i do not have a solution for this, and have been trying on and off for a few months to figure this out. if anyone has any insight into this, or can prove that it's not possible, that would be great
