Derivatives and Differentials

Differentials and Derivatives

A. Letters u and v denote independent variables or functions of an independent variable; letters a and n denote constants.

B. To obtain a derivative, divide both members of the given formula for the differential by du or by dx.

Differentiation of Integrals:

If f is continuous, then

Chain Rule:

If y = f(u) and u = g(x), then
