can someone link/show me a formal proof of the multivariable chain rule?
let x be a vector x=(x1,x2,...,xn)what? how is this multavariable?
yea i thought of that and thought the same thing; that there's gotta be a more rigorous proof.There must be a better proof of the chain rule than that.
more rigorous than very rigorousyea i thought of that and thought the same thing; that there's gotta be a more rigorous proof.
