Hello, My name is Ryan and I use desmos frequently in my classroom. I was wondering if there is any way to place imaginary numbers or complex numbers into desmos like you can with the TI calculators when you change the mode from real to a + bi? If so this would be very helpful for those students who do not have calculators of their own to work at home on our remote days or for homework.
Hi Ryan, as best as I can tell, Desmos does not currently support complex numbers but has received some requests to add support for them (e.g. this tweet). You’re definitely welcome to re-request this feature so it gets more attention!
You can make Desmos activities that handle specific uses for complex numbers - it would be quick to make an activity that adds complex numbers, for example - or to avoid reinventing the wheel you can direct your students to other online resources like Symbolab or WolframAlpha.
The idea of using Desmos to create a complex number calculator tickled my fancy, so here’s a prototype:
I’m sharing this mostly as a curiosity - if I were sharing a resource for my students, I’d share one (like one linked above) that’s better than this
