Second and higher order partial derivatives are defined analogously to the higher order derivatives of univariate functions. For the function the "own" second partial derivative with respect to x is simply the partial derivative of the partial derivative (both with respect to x): The cross partial derivative with respect to x and y is obtained by taking the partial derivative of f with respect to x, and then taking the partial derivative of the result with respect to y, to obtain

The cross partial derivative with respect to x and y is obtained by taking the partial derivative of f with respect to x, and then taking the partial derivative of the result with respect to y, to obtain

A brief overview of second partial derivative, the symmetry of mixed partial derivatives, and higher order partial derivatives.

They are found similarly to f_xx or f_yy. For example to find f_xy first differentiate with respect to x, holding y constant, to obtain f_x.

Cross partial derivative: fxy = ∂fx / ∂y, where f (x) is the first derivative with respect to x. fyx = ∂fy / ∂x, where f (y) is the first partial derivative with respect to y. However, an online Directional Derivative Calculator determines the directional derivative and gradient of a function at a given point of a vector. Example:

More precisely, walk along the path lying over t↦(x0,y0+t) and observe the rate of change of t↦fx(x0,y0+t). That's the cross partial derivative at (x0,y0) ...

order cross-partial derivative. This is defined as. This tells us how the slope of the function with respect to x1 changes as we.

If the function involved has sufficient continuity, cross derivatives, meaning those which involve differentiation with respect to more than one variable, yield ...

First, take the partial derivative of z with respect to x. Then take the derivative again, but this time, take it with respect to y, and hold the x constant.

Taking first derivatives leads to the results shown in part B; by taking cross derivatives in either order, one obtains the so-called Maxwell relations shown in part C. Once the equation of state P = P(T,V) or V = V(T,P) is known, one can integrate [I.10] and [I.12] to find S …
