At t = 0 the switch is closed and current passes through the circuit. The order of a differential equation is the highest order derivative occurring. Another reason for the interest in reaction–diffusion systems is that although they are nonlinear partial differential equations, there are … 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. Application 1 : Exponential Growth - Population Let P(t) be a quantity that increases with time t and the rate of increase is … is positive and since k is positive, P(t) is an increasing exponential. Other applications of reaction–diffusion equations include ecological invasions, spread of epidemics, tumour growth and wound healing.
