WebThe bigger the population, the more new rabbits we get! When the population is 2000 we get 2000×0.01 = 20 new rabbits per week, etc. So it is better to say the rate of change (at any instant) is the growth rate times the population at that instant: dNdt = rN. And that is a Differential Equation, because it has a function N(t) and its derivative.
