Differential Equations and Population Growth
The size of a population at any given time depends upon the rate at which the population is growing. The rate at which a population grows changes with time, therfore, the population does not always grow by the same amount over equal intervals of time. It is the goal of this lesson to solve population problems for populations that grow at a changing rate.
To solve population problems in which the population grows at a rate thea is directly proportional to the number of members present in the population
For a population that grows at a rate that is directly proportional to the number of members present in the population:
1. calculate the size of the population at a given time,
2. calculate the time at which the population will be a given size.
