equation. 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

1.1 Solving an ODE. Simulink is a graphical environment for designing simulations of systems. As an example, we will use Simulink to solve the first order differential equation (ODE) dx dt = 2sin3t 4x. (1.1) We will also need an initial condition of the form x (t0) = x0 at t = t0. For this problem we will let x (0) = 0.
