Before analyzing the solutions to the nonlinear population model, let us make a pre-liminary change of variables, and set u(t) = N(t)/N⋆, so that u represents the size of the population in proportion to the carrying capacity N⋆. A straightforward computation shows that u(t) satisfies the so-called logistic differential equation du dt
