The main thing I use Desmos for is coding. Many see the graphing calculator as a way to solve problems and create art, but I found out, along with many others, that there is built in coding features! You can use {} as if statements, and actions, or ->, can change variables. Tickers can be used as timers, gameticks, and many other things. Here are some links from the Desmos website to learn more:

Although I don't do it much, many people create art in desmos. Check out the links above for information useful for creating art! (Custom colors, restrictions, polygons)
