Population growth of any species is frequently modeled by an ODE of the form dN - = aN – bN² N(0) = No dt where N is the population, aN represents the birthrate, and death rate due to all causes, such as disease, competition for food supplies, represents the and so on. If N, = 100,000, a = 0,1, and b = 0.00008, calculate N(t) using fourth order Runge-Kutta method for t = 0.0 to 20.0 years with h = 4.

Question
Population growth of any species is frequently modeled by an ODE of the form
dN
- = aN – bN?
N(0) = No
dt
where N is the population, aN represents the birthrate, andI
represents the
death rate due to all causes, such as disease, competition for food supplies,
and so on. If N, = 100,000, a = 0,1, and b = 0.00008, calculate N(t) using
fourth order Runge-Kutta method for t = 0.0 to 20.0 years with h = 4.
