WebSubstituting this Figure for the f(N) (which is the function that the intrinsic rate of increase is) gives us our final result, the famous logistic equation that describes logistic population … 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. WebApr 23, 2012 · A simple equation for population projection can be expressed as: Nt=Pe rt. In this equation, (Nt) is the number of people at a future date, and (P) is equal to the present population.
