I’ve spent three years asking audiences if anyone does an integral or derivative by hand. Other than hs calc teachers, absolutely no one does. Its role is to weed people out.https://twitter.com/54sensaicrone/status/996398066260434945 …
I do, & I'll never teach calculus. This is a poorly framed question, since it presumes there is one correct way to teach. Learning these things well creates a valuable intimacy (cc @rmozone). But that doesn't mean more than a small minority of people should learn them well.
