Solution of First Order Linear Differential Equations Linear and non-linear differential equations A differential equation is a linear differential equation if it is expressible in the form Thus, if a differential equation when expressed in the form of a polynomial involves the derivatives and dependent variable in the first power and there are no product […]. The cascade is modeled by the chemical balance law rate of change = input rate − output rate. Comparing Linear and Nonlinear Differential Equations of DTM.
