1
State the central method of Logistic Growth & Carrying Capacity and list the conditions that must be checked.
Faculty solution: Use modelling self-limiting proportional growth. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
For P′=.2P(1−P/1000), when is growth fastest?
Faculty solution: At P=K/2=500.
3
What is the long-run population for positive initial data?
Faculty solution: P approaches K=1000.
4
A learner makes an error by ignoring initial conditions, step size, equilibria, or model residuals. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is ignoring initial conditions, step size, equilibria, or model residuals. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of Logistic Growth & Carrying Capacity in population, cooling, mixing, finance, medicine, circuits, and resource systems. Define variables and identify the quantity an integral, differential equation, sequence, or series would measure.
Faculty solution: A defensible response defines variables and units, states assumptions, builds the correct mathematical object, and interprets its value in population, cooling, mixing, finance, medicine, circuits, and resource systems.
6
Describe two independent ways to verify a result from Logistic Growth & Carrying Capacity.
Faculty solution: Use an exact structural check such as differentiation, substitution, partial sums, or theorem hypotheses; then compare with numerical, graphical, dimensional, or limiting evidence.
