I don't know since how long this was already available, but #Desmos has now a 3D Plot version.
Stupid #math of the day: graphing the distance to the floor according to the stretching of the muscle when doing a split.
If I didn't mess anything, the green curve hints that the distance to the floor remains roughly linearly correlated with the stretch of the muscle as we get closer and closer to the ground.
Which means if progress slows down it's essentially due to the muscle being harder to stretch and not because of angle illusion or something :(
Alright, I think I finally have a decent sandbox for my 1D signed distance debugging.
A few seconds after I finally managed to hack a gradient in #desmos the website crashed my session (can't access the website anymore unless logged of)
Anyway, that's starting to be a pretty good sandbox for debugging 1D signed distances.
The gradient trick: rgb() and hls() create colors but you can't use a continuous value such as x, so you sample them like a cavem^Wengineer on the x-axis. Then you use t for a constant continuous y-axis value: (G,t), which you can then move around

So we get the right answer(!) UNLESS there's more than 1 term following the slash, in which case it puts ALL of them in the denominator, so we're back to wrong answers. So you CAN get the right answer, but ONLY if you use a slash, and ONLY if there's only 1 term following it.
So for those who claim "e-calculators do it correctly", how is it that they're all doing it DIFFERENT ways?? There is only 1 correct way to do it, and only #MathGPT does it that way (looking at you #Desmos)...
#Desmos USED TO give the correct answer (many teachers use it. I USED TO, but it's useless now - can't type in what's in the textbook, have to add extra brackets to make it work and do what's in the textbook correctly). I know one of the changes which broke it too. To make 8/2 a fraction (not division) you had to put brackets. i.e. (8/2). They changed it so that it automatically turns 8/2 into a fraction, which is cool, but unfortunately it ALSO turns 8÷2 into a fraction, which is wrong...

A couple of Desmos Classroom activities for repeated practice: finding the distance and midpoint between points, and determining if two lines are parallel, perpendicular, or neither.
I've nudged this #PowerAutomate flow for #Desmos to allow you to use either Chrome or Edge browser.
I revised "Desmos2OneNote" (which captures a student's #Desmos screens and creates a OneNote Page of them) to take advantage of some #PowerAutomate improvements -- and found a way to share it with others.
If you try it, let me know how it goes! https://onenoteschool.com/desmos2onenote-version-2/ #mtbos
Ever wondered why electrical systems have 3 sinusoidal phases? Why generators are typically built with 3:4 coils:magnets. I graphed the magnetic field strength at various phases to find out: https://www.desmos.com/calculator/buqj2pdezs
Nutzt du es noch? Hat die Schule Data Protection Addendum (DPA) und EU Standard Contractual Clauses (SCCs) https://www.desmos.com/privacy-pdfs/Desmos_DPA_and_SCC_2021-06-17_v3.pdf mit Desmos abgeschlossen?
Leider ist mir keine Alternative bekannt. Ich hätte das gerne in deutsch auf EU Servern als OpenSource. 😁
Today I am thrilled to be able to share something we at #Desmos Studio have been working on for the past year: a brand new #geometry construction tool. What makes me particularly excited about this product is that we built in robust #keyboard and #ScreenReader support from the start and leveraged #accessible markup everywhere we could. This very well may be the first #accessible digital geometry tool ever built, and we'd love your feedback.
It now has...
* optional shading to smoothly illustrate the net amplitude in different areas.
* the choice between exact hyperbolic solutions for the maxima or the approximate linear maxima regions typically discussed in double-slit interference
* a single curve/ray at an order/path-difference of your choice even if it's not an extremum
For my #genuary31 contribution, I reflect on #genuary2023 and how it is coming to a close – I did all but generative music in #desmos – and here are three contributions that gave me the most joy

Here is my #genuary19 (Black and white) constribution to #genuary2023 created in #Desmos. Based upon flips of 10 coins, plotting the difference between head/tails. I had two versions: one without filling and one with. A student liked the with, so shared that.
Playing some What-If-Not games with my genuary16 contribution with some unexpected surprises
created with #desmos
Here are 2 interactive #desmos demos to play with to get comfortable with 1 and 2 points linear perspective. I don't know if that helps much, but it was a lot of fun to make.
The 3+ points perspectives are left as an exercise to whoever wants to do it.
I don't think people realize how fantastic #desmos can be. Here is an example to show how easy it is to create a draggable point within constraint. Very few software seem to be able to do that.
What's also incredible about this is that it really feels like doing #math because there is no discrete BS such as "let's create a 3000 points array to evaluate my curve smoothly".
Having a continuous approach and implicit dependency tree just blows my mind.
Here’s my #introduction post. I’m a high school teacher in the SF Bay Area, with three kids (8, 6.5, and 3.5). Currently, I spend most of my time teaching or parenting. I thought joining this sfba instance might help me connect with more people in the area. I enjoy drinking good #tea, making #Desmos activities (it’s a math teacher thing #mtbos), reading (though mostly just audiobooks these days), #crosswords, music, cooking, hiking, etc.
