The population, P(t), of fish in a lake is modeled by the equation dP/dt =3P-2.4*10-4P2. If this population begins with 500 fish when will the population of fish reach 10 thousand?
The survival of two species depends on their mutual cooperation. For instance, a species of bee that feeds primarily on the nectar of one plant species and simultaneously pollinates the plant. One simple model of mutualism is given by
dx/xt = −ax + bxydy/dt = −my + nxy
where a, b, m, and n are all positive constants.
Perform a graphical analysis and indicate the trajectory directions in the phase plane.
