Graphing phase portraits
WebA phase portrait is a geometric representation of the trajectories of a dynamical system in the phase plane. Each set of initial conditions is represented by a different curve, or point. Phase portraits are an … WebSince we have complex conjugate, with positive real part, these are unstable spirals and that is what the phase portrait is telling us. Here is a handy stabilty reference classifying eigenvalues. So, we need to learn to …
