## 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 | |||||
