For the kind of functions seen in American math curricula, no, I don’t need help visualizing them, but that’s me. However, I do believe one should develop their intuition through graphing by hand; typing into the calculator, however painful, doesn’t develop anything other than RSI. I think my TI (yeah I did have one as the prize of some math competition...) could do some integration too but I never used it. The thing is these crappy calculators do a poor job of pretty much everything they claim to do. Some of the functionality might help with learning, sure, but you’d better use an actual computer (including a modern smartphone). It’s not 1980s anymore...
