Consider a population P(t) that is varying with time. A mathematician will say that the rate at which the population is changing with respect to time is given by the derivative dP dt On the other hand, a population biologist will say that the rate of change is roughly proportional to the population. This means that there is a constant r, called the reproductive rate, such that...
