Webd p d t = r p, p ( 0) = p 0. where p is the population of bacteria and t is time in hours with the present time being set to t = 0. This is a separable first order differential equation and we can solve it to find. p = p 0 e r t. … WebClearly, then, the rate of change of the population, or the growth rate, would be represented by the quantity dp/dt, or p'. Introducing these quantities, Malthus' idea becomes: dp/dt= k p. This differential equation is quite easy to solve, but by itself it will yield a whole family of solutions.
