How to solve logistic differential equation
WebSolving the Logistic Differential Equation Since we would like to apply the logistic model in more general situations, we state the logistic equation in its more general form. The logistic equation The logistic equation is dP dt = kP (N −P). (8.9) (8.9) d P d t = k P ( N − P). WebAll solutions to the logistic differential equation are of the form P ( t) = M 1 + A e − k t where A is some constant that depends on the initial condition. No matter what the constant A …
