Birth rates around that time ranged from 35 to 40 million per year and death rates ranged from 15 to 20 million per year. Let's assume that the carrying capacity for world population is 20 billion (a) Write the logistic differential equation for these data. (Because the initial population is small compared to the carrying capacity,...
