  1. Consider the system;

dx/dt=x(1-x/10)-1/2xy

dy/dt=2y(1-y/6)-xy

(a) Find all equilibrium solutions.

(b) Draw the phase plane.

(c) On the phase plane, mark
• all equilibrium solutions.

• the lines where dx/dt =0, dy/dt =0

• an arrow indicating the general direction of the flow of the system in each region on the picture.

(d) If you were given initial conditions x = 3 and y = 4, what do you think would happen to the solution?

dx dt =ax+by dy dt =−x − y, 2. As the values of a and b are changed so that the point (a,b) moves from one region to another, the type of the linear system changes, that is, a bifurcation occurs. Which of these bifurcations is important for the long-term behavior of solutions? Which of these bifurcations corresponds to a dramatic change in the phase plane or the x(t)and y(t)-graphs?
