In Sec. 2.6 we introduced the Lotka-Volterra predalor-prey system
x' =(a -by)x.
y' = (ex - d)y.
and determined its equilibrium points (0. 0) and (d/c, a/b). Use the Jacobian matrix to analyze the stability around the equilibrium point (d/c, a/b). lnterprel the trajectories of this system as plotted in Fig. 2.6. 7.
