- a function of two variables that is obtained from a given function, y = f(x), and that expresses the approximate increment in the given function as the derivative of the function times the increment in the independent variable, written as dy = f′(x)dx.
- any generalization of this function to higher dimensions.
- the difference involved in a differential rate.
