If it runs Python, then couldn’t you use SymPy as a CAS (in addition to NumPy, seaborn, etc. for numerical computing / visualization)? By the way, I like the idea of this calculator and hope to see more like it. I think something that combined this with ideas from WolframAlpha (natural language CAS, problem explainers and expanders) and Khan Academy (spaced repetition, gamification of learning, progression of tutorial videos, practice and diagnostic problems) would be really powerful. In fact I became temporarily obsessed with the idea of creating this sort of calculator >10 years ago when taking multivariate calculus and struggling to visualize or understand the problems. Yes, you could always use a computer/tablet/phone, but as someone who struggles with ADD, there is a lot to be said for using a constrained learning tool, so that the versatile (read: distracting) devices can be put out of sight during dedicated study time.
