"Webx ( t) = c t + x 0. Similarly, we can write the proportional growth model like this: Δ x Δ t = α x. And as a differential equation like this: d x d t = α x. If we multiply both sides by d t and divide by x, we get. 1 x d x = α d t. Now we integrate both sides, yielding: ln x = α t + K. " - Population logistic growth
