Chapter 2.1, Problem 18P

Program Plan Intro

Program Description: Purpose of problem is to show that the threshold population is $M=\frac{D_0{P}_0}{B_0}$ , if the extinction explosion equation is $\frac{dP}{dt}=a{P}^2-bP$ , where $B=a{P}^2$ is the time rate at which births occur and $D=bP$ is the rate at which deaths occur, initial population is $P_0$ , and $B_0$ births per month and $D_0$ deaths per month are occurring at time $t=0$ .
