parts (abcd) of 1 A EXERCISES 1. For each of the following nonlinear systems: (a) Find all the critical points. (b) Use the Jacobian matrix to classify the critical points (saddle, node, etc., stable, asymptotically stable, etc.) (c) In the phase plane sketch the nullclines and indicate the direction field in regions bounded by the null- clines. (d) Insofar as possible, sketch a rough phase diagram indicating several key orbits.
