## partial derivativeThe 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 D_{x}f and D_{y}f, or f_{x} and f_{y}. The partial derivative of a variable with
respect to time is known as the local derivative.## Related category• CALCULUS AND ANALYSIS | |||||
