\frac{dP}{dt}=rP\left(1-\frac{P}{K}\right)Variables
- P: population
- r: intrinsic growth rate
- K: carrying capacity
- t: time
How to use this formula
Models growth that slows as a population approaches carrying capacity.
Important notes
- P=0 and P=K are equilibrium solutions.
- The model assumes a constant carrying capacity and homogeneous population.
Quick example
When P=K/2, the growth rate is rK/4.
Applicability, worked calculation, and verification
Assumptions and domain checks
- P=0 and P=K are equilibrium solutions.
- For the Logistic Differential Equation, every denominator must be nonzero, and the numerator and denominator must remain correctly grouped.
- State the domain together with any initial or boundary conditions, and confirm the regularity assumptions required by the method.
Worked example
When P=K/2, the growth rate is rK/4.
Common mistakes
- When copying Logistic Differential Equation, keep the complete numerator and denominator grouped; a missing brace or parenthesis changes the result.
- Do not present a general solution as the requested solution before applying all initial or boundary conditions.
