480 Graphs & Geometry
In this example, manipulating the intial term demonstrates that the
point of equilibrium in the rabbit and fox populations over the cycle
of 400 generations = (150, 50).
Graphing differential equations
You can study linear and non-linear differential equations and systems of
ordinary differential equations (ODEs), including logistic models and
Lotka-Volterra equations (predator-prey models). You can also plot slope
and direction fields with interactive implementations of Euler and
Runge-Kutta methods.
