Derivative of logistic growth function
WebJul 5, 2024 · As before, just recognizing that this is a logistics growth model is key. This time, though, we have the “solution” function rather than the differential equation. But just compare this to the known solution, identifying M = 108,000 and b = 17. The carrying capacity is M = 108,000. The initial population is a = M / (1+ b) = 108,000/ (1 + 17 ... WebAug 3, 2024 · A logistic function is an S-shaped function commonly used to model population growth. Population growth is constrained by limited resources, so to account for this, we introduce a carrying capacity of the system , for which the population asymptotically tends towards. Logistic growth can therefore be expressed by the following differential …
