Another model for a growth function for a limited population...

Another model for a growth function for a limited population is given by the Gompertz function, which is a solution of differential equation $ \frac {dP}{dt} = c \ln (\frac {M}{P})P $ where $ c $ is a constant and $ M $ is the carrying capacity. (a) Solve this differential equation. (b) Compute lim $ _{t \to \infty} P(t). $ (c) Graph the Gompertz growth function for $ M = 1000, P_0 = 100, $ and $ c = 0.05, $ and compare it with the logistic function in Example 2. What are the similarities? What are differences? (d) We know from Exercise 13 that the logistic function grows fastest when $ P = M/2. $ Use the Gompertz differential equation to show that the Gompertz function grows fastest $ P = M/e. $
