List of differentiation identities

List of differentiation identities

The primary operation in differential calculus is finding a derivative. This table lists derivatives of many functions. In the following, "f" and "g" are differentiable functions, from the real numbers, and "c" is a real number. These formulas are sufficient to differentiate any elementary function.

General differentiation rules

;Linearity:left({cf} ight)' = cf':left({f + g} ight)' = f' + g';Product rule:left({fg} ight)' = f'g + fg';Reciprocal rule:left(frac{1}{f} ight)' = frac{-f'}{f^2};Quotient rule:left({f over g} ight)' = {f'g - fg' over g^2}, qquad g e 0;Chain rule:(f circ g)' = (f' circ g)g';Derivative of inverse function:(f^{-1})' =frac{1}{f' circ f^{-1for any differentiable function "f" of a real argument and with real values, when the indicated compositions and inverses exist.;Generalized power rule:(f^g)'=f^g left( g'ln f + frac{g}{f} f' ight)
