Generalizing the second derivative. Consider a function with a two-dimensional input, such as. . Its partial derivatives and take in that same two-dimensional input : Therefore, we could also take the partial derivatives of the partial derivatives. These are called second partial derivatives, and the notation is analogous to the notation for ...

A second order partial derivative is simply a partial derivative taken to a second order with respect to the variable you are differentiating to. As an example, let's say we want to take the partial derivative of the function, f (x)= x 3 y 5, with respect to x, to the 2nd order. This is represented by ∂ 2 f/∂x 2 .

There is a theorem, referred to variously as Schwarz's theorem or Clairaut's theorem, which states that symmetry of second derivatives will always hold at a point if the second partial derivatives are continuous around that point. To really get into the meat of this, we'd need some real analysis.
