Logistic equation of population growth
WitrynaWe can incorporate the density dependence of the growth rate by using r(1 - P/K) instead of r in our differential equation:. In some textbooks this same equation is … WitrynaTo solve this equation, we multiply both sides by d t: d x = c d t And then integrate both sides: x ( 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
