I used Desmos quite a bit as an instructional tool for high school math. They are funded through relationships with several companies, but most notably the standardized testing industry, which uses it with their online tests.<p>Over ten years before Desmos launched, there began an open source project called Geogebra (<a href="https://www.geogebra.org/" rel="nofollow">https://www.geogebra.org/</a>). Geogebra remains open source to this day and offers a similar suite of applications and calculators, both online and in app form.<p>Over the years I have also used Geogebra as an instructional tool in both my math and physics classrooms, producing dozens of apps, simulators, and gizmos: <a href="https://www.geogebra.org/u/mrdathhs" rel="nofollow">https://www.geogebra.org/u/mrdathhs</a><p>Geogebra excels at creating mathematical simulations. One of my favorites was this real-time satellite orbit calculator: <a href="https://www.geogebra.org/m/UEynuRnG" rel="nofollow">https://www.geogebra.org/m/UEynuRnG</a>
I really wish I could get a dedicated handheld graphing calculator that hasn't had most of the functionality removed due to standardized testing. We live in an age of miracles but having a decent solver on a dedicated device is apparently commercially impossible because it couldn't be sold to students.<p>I'm just a dude in my shop that occasionally would like to integrate a thing or two without getting coolant on my phone.
I posted on Mastodon today about how helpful tools like this are for building mathematical intuition. Animations are no substitute, but they can also do what lecture never could.<p>Mastodon post:

High school students taking the digital SAT get near-full access to Desmos throughout the math portion of the test (it’s a modified version, but you get access to practically everything). It’s very powerful, and if you can use it effectively, you can brute force hard questions in seconds. Graphing calculators have been available during the SAT in the past, but Desmos is something else… I wonder how it effects score distributions/question difficulty.
Awesome. I love desmos. I just used it yesterday for a Wave mathematics class I taught for a homeschool group. I also wrote a math graphing program that helps make math beautiful called [Truthy Graph](<a href="https://truthygraph.github.io/" rel="nofollow">https://truthygraph.github.io/</a>). It came from a thought: most graphing programs only graph were both sides of the equation are exactly equal, but what would it look like to see also where they are nearly equal (in other words, the error gradient)?
For a similar project in a similar space (but with both a free android emulator, and the option for a dedicated hardware device), see [0]. I actually use it as my preferred calculator on my phone.<p>All the best,<p>[0] <a href="https://www.numworks.com/" rel="nofollow">https://www.numworks.com/</a>

If you're interested in conlangs, someone made a language, Grapherit [0], that is "spoken" via the Desmos graphing calculator.<p>[0]: <a href="https://m.youtube.com/watch?v=HP3nIDAhwYo" rel="nofollow">https://m.youtube.com/watch?v=HP3nIDAhwYo</a>
We are in kind of similar category but broader data literacy space and making data analysis more accessible and interactive. give it a try at <a href="https://tuvalabs.com" rel="nofollow">https://tuvalabs.com</a><p>you can plot functions on top of your visualizations, or take samples etc.
Some crazy hacker has even used the calculator UI to implement a Sudoku game: <a href="https://www.desmos.com/calculator/vg3vye1rvm" rel="nofollow">https://www.desmos.com/calculator/vg3vye1rvm</a>
Des os is the best graphic calculator ever built.
And its amazing it has un directly in your browser or without internet on your phone.<p>Just wish it was open source :-)<p>Anyone know of an open source library like 3blue1brown Manim library that can work run client side in the web browser like Desmos ?
Desmos is a great tool a nice trick I learned late during my undergrad is that desmos copy/paste gives Latex<p>So a pretty well featured latex equation builder is always a click away if you’ve got a graphing calculator bookmarked in your browser<p>Same thing with symbolab if I recall and a handful of other web based math tools
