Logistic Growth Model
Model population growth with limited resources using the logistic differential equation dP/dt = kP(1 - P/M), where M is the carrying capacity. Visualize the S-shaped logistic curve P(t) = M/(1 + Ae^(-kt)) and understand how growth rate is fastest at P = M/2. Explore applications in ecology, epidemiology, and economics where growth is constrained by environmental factors, resource availability, or market saturation.
Euler's Method Simulator
Approximate solutions to differential equations using Euler's method, a numerical technique that uses tangent line approximations. Starting from an initial condition, iteratively calculate y_{n+1} = y_n + f(x_n, y_n)·Δx to trace the solution curve. Visualize how smaller step sizes improve accuracy, understand accumulation of error, and explore applications where analytical solutions are difficult or impossible to find.
