First order systems have primary elements such as generic flows and driving forces, as well as derived quantities such as capacitance and resistance. A text on control theory (Coughanowr and Koppel, 1965) describes the latter two quantities as primary elements denoted in differential form. This work extends that differential concept to nonlinear first order systems. Results of classical linearization theory (for example, linearized time constants) are then obtained with more ease.
