Sketch the phase portrait of a planar system having = (a) a trajectory T with a(T) = w(T) = {xo}, but I # {xo}. a (b) a trajectory r such that w(r) consists of one limit orbit (cf. Example 1). (c) a trajectory I such that w(r) consists of one limit orbit and one equilibrium point. (d) a trajectory I such that w(r) consists of two limit orbits and one equilibrium point (cf. Example 2 in Section 2.14 of Chapter 2). (e) a trajectory I such that w(T) consists of two limit orbits and two equilibrium points (cf. Example 1 in Section 2.14 of Chapter 2). (f) a trajectory I such that w(T) consists of five limit orbits and three equilibrium points.
