Q: A population of animals live on an isolated island such that at any time, the number of births per unit time is proportional to the population and the number of deaths per unit time is proportional to the square of the population. If the population at time t is x and the population is changing at the greatest rate when x = 1, show that
where k is positive constant.
(I have done the showing step, but I don't know how to solve the following parts.)
i) Find the general solution of the differential equation in terms of k.
ii) Show that there is a limit to the size of the population.
Pleas help! Thank you!
