Part 5: The Effect of Hunting Predators (Optional)
Suppose that predators are removed from the population at a regular rate by hunting, say, at 5 per year. Then the predatorprey model takes the form
dx/dt = ax  bxy,
dy/dt = cy + pxy  5,
where a, b, c, and p are the growth and interaction parameters as before. As in Part 4, you may use your choice of graphical representation to determine the significance of this change.
