Hence, Newton’s Second Law of Motion is a second-order ordinary differential equation. There are many applications of DEs. Growth of microorganisms and Newton’s Law of Cooling are examples of ordinary DEs (ODEs), while conservation of mass and the flow of air over a wing are examples of partial DEs (PDEs).

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. The solution to the above first order differential equation is given by.

elliptic and, to a lesser extent, parabolic partial differential operators. Equa-tions that are neither elliptic nor parabolic do arise in geometry (a good example is the equation used by Nash to prove isometric embedding results); however many of the applications involve only elliptic or parabolic equations.

THE NATURAL GROWTH EQUATION The natural growth equation is the differential equation dy = ky dt y where k is a constant. Its solutions have the form k>0 y = y0 ekt where y0 = y (0) is the initial value of y. y = ekt t The constant k is called the rate constant or growth constant, and has units of y inverse time (number per second).
