1. (This is problem 5 from the second assignment sheet, reprinted here.) Consider the nonlinear system a. Sketch the ulllines and indicate in your sketch the direction of the vector field in each of the regions b. Linearize the system around the equilibrium point, and use your result to classify the type of the c. Use the information from parts a and b to sketch the phase portrait of the system. 2. Sketch the phase portraits for the following systems...

In this problem, you will get more experience with taking
derivatives with respect to vectors by proving
common identities. In the following, it will be useful to
remember that if x = (x1, . . . , xn)^⊺ and y =(y1, . . . , yn)^⊺
are vectors, then the dot product x^⊺y is a scalar equal to
