If mixed partial derivatives are the same, this means that functions of this derivatives are continuous. Does this mean that also a function f is continuous in the same point?

Best ResponseYou've already chosen the best response.0If the partial derivatives of a function \[ f : \mathbb{R}^n \rightarrow \mathbb{R}^m \] exist and are continuous at a point p, then the function is differentiable at p. If the function f is differentiable at p, then it is continuous at p.
