In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Learn more about Chapter 12: Applications of First-Order Differential Equations on GlobalSpec. Almost all of the differential equations whether in medical or engineering or chemical process modeling that are there are for a reason that somebody modeled a situation to devise with the differential equation that you are using. The parameter that will arise from the solution of this first‐order differential equation will be determined by the initial condition v(0) = v 1 (since the sky diver's velocity is v 1 at the moment the parachute opens, and the “clock” is reset to t = 0 at this instant). Differential equation can further be classified by the order of differential. It is very common to see individual sections dedicated to separable equations, exact equations, and general first order linear equations (solved via an integrating factor), not necessarily in that order. Application 1 : Exponential Growth - Population Let P(t) be a quantity that increases with time t and the rate of increase is proportional to the same quantity P as follows d P / d t = k P where d p / d t is the first derivative of P, k > 0 and t is the time.
