Hey, everyone. I've been doing my Calculus II homework, and I've been trying these two problems for the past few hours, but I can't even seem to get started on them. A friend of mine recommended I try here because you guys are awesome. 1. The problem statement, all variables and given/known data The Gompertz equation dP/dt = P(a - b ln(P)) where a and b are positive constants, is another model of population growth. a) Find the solution of this differential equation that satisfies the initial condition: P(0) = p(sub(0)) b) What happens to P(t) as t -> infinity? c) Determine the concavity of the graph of P 2. The attempt at a solution dP/dt = P(a - bQ) where Q = ln(x) 1. The problem statement, all variables and given/known data the differential equation dP/dt = P(10^-1 - (10^-5)P) models the population of a certain community. Assume P(0) = 2000 and time t is measured in months. a) Find P(t) and show that lim t -> infinity exists b) Find the limit 2. The attempt at a solution I do not even know where to start on this. Any help at all would be nice.
