See all on Wikipediahttps://en.wikipedia.org/wiki/Partial_derivativeIn mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). Partial derivatives are used in vector calculus and differential geometry. The … See more
Like ordinary derivatives, the partial derivative is defined as a limit. Let U be an open subset of and a function. The partial derivative of f at the point with respect to the i-th variable xi is defined as

When writing PDEs, it is common to denote partial derivatives using subscripts. For example:
The Greek letter Δ denotes the Laplace operator; if u is a function of n variables, then
A PDE is called linear if it is linear in the unknown and its derivatives. For example, for a function u of x and y, a second order linear PDE is of the form
