Partial Derivative

The ordinary derivative
of a function of two or more variables with respect to one of the variables,
the others being considered constants. If the variables are x and y
, the partial derivatives of f(x, y) are written Δf/Δx
and Δf/Δy, or Dxf and Dyf, or fx
and fy.

The partial derivative of a variable with respect to time is known as
the local derivative.
