3.3: The following system of equations is a model for the populations of two species that compete
for limited resources.
x'(t) = 2x(1 –
- )- »
- xy
y'(1) = 3y (1 –
) –
- 2.xy.
Find and sketch the nullclines and find any equilibrium values. Use the nullclines to sketch the
phase plane, indicating the trajectories of several possible solution. Based on your sketch, what can
you say about the stability of the equilibria?
