howellkb.uah.edu/DE2/Lecture Notes/Part6_Systems/NLS1.pdf11.04.2014 · This gives us a third critical point, (3,2). In summary, our system of differential equations has three critical points, (0,0) , (0,1) and (3,2) . No other choices for (x, y) will satisfy algebraic system (43.2) (the conditions for a critical point), and any phase portrait for our system of differential equations should include these
