(a) Show that solution trajectories on the boundary of the square with vertices (-2, –2), (-2, 2), (2, –2) and (2, 2) are directed into the interior of the square (consider each edge separately). (b) Show that r' > 0 for some appropriate value of the polar coordinate r. (Note that it won't be necessary to deal with the o equation.) (c) What do the results of parts (a) and (b) tell you about the existence of a periodic solution?
