OK, now it's time to see how multi-index notation works with derivatives. We'll see that an operator notation is very efficient, thanks the the delightful fact that mixed partial derivatives commute.

aw man I was getting excited thinking there were gonna be tensors since we need higher order derivatives

Regarding the stipulation about continuity, am I recalling correctly that we are saying f is C^2?

Recalling what you said in case f has multiple outputs, just treat the components one at a time, but is this going to start looking like some kind of matrix when we actually Taylor it? Or are the outputs just independent, each with their own TS?
