Certainly, everyone interested in technology should possess an understanding of the models of deterministic, continuous multivariable control. The study of multivariable calculus can be viewed as a natural extension of the unfortunately named "single variable" calculus. Ordinary "single variable" calculus is the study of equations in two variables, F(x, y) = 0. Equations in two variables provide mechanisms for studying: a) continuous curves in the two dimensional plane, b) continuous models of control (where one variable controls a second variable), c) continuous models of time variation (signals, trends or evolution) or d) situations where two variables track together continuously.
