An overview of the second partial derivative, the symmetry of mixed partial derivatives, and higher-order partial derivatives.
Partial Derivatives : Higher Order
1. Introduction
A function e.g f(x,y) or z(x,y)
2. Second Partial Derivatives
Taking two consecutive partial derivatives with respect to the same variable
Standard Notation
fxx
fyy
3. Mixed Partial Derivatives
Taking partial derivatives with respect to one variable, and then take another partial derivative with respect to a different variable
fyx
fxy
Del Notation
Subscript Notation
4. Higher Partial Derivatives
Mixed partial derivatives give same result whenever :
f, fx, fy, fxy, fyx
Third and higher order :
fyyx
fyyxx
Engineering Applications
