WebOct 17, 2024 · The logistic equation is an autonomous differential equation, so we can use the method of separation of variables. Step 1: Setting the right-hand side equal to zero gives P = 0 and P = 1, 072, 764. This means that if the population starts at zero it will never change, and if it starts at the carrying capacity, it will never change.
