The second derivative generalizes to higher dimensions through the notion of second partial derivatives.
Partial derivatives are used in vector calculus and differential geometry.

New hierarchies of integrable equations in partial derivatives coinciding with the integrable modification of the non-abelean Toda equations are constructed.
These methods are called differential since they are based on local Taylor series approximations of the image signal; that is,they use partial derivatives with respect to the spatial and temporal coordinates.
In contrast to functions of one variable, the existence of both partial derivatives of the first order for a function of two variables still does not guarantee its differentiability.
If the function f: Rn→ R is k+ 1 times continuously differentiable in the closed ball B, then one can derive an exactformula for the remainder in terms of(k+1)-th order partial derivatives of f in this neighborhood.
Two types of derivatives are used: Partial derivatives are denoted either by the operator∂ i{\displaystyle\partial_{i}} or by subscripts preceded by a comma. Covariant derivatives are denoted either by the operator∇ i{\displaystyle\nabla_{i}} or by subscripts preceded by a semicolon.
For a continuously differentiable function of several real variables, a point P(that is a set of values for the input variables, which is viewed as a point in Rn)is critical if all of the partial derivatives of the function are zero at P, or, equivalently, if its gradient is zero.
Below is a typicalformula entry in& kformula;. To enter the partial derivatives and Greek letters click on the symbol combo box, on the right, and select the appropriate symbol. The symbol combo box, in the figure below, has the word Cap on it. Click on the return key symbol to the right of it, to enter a symbol.
