To find fixed points, draw nullclines, vector fields, and phase portrait of the given differential equation system. Concept Introduction: Fixed point of a differential equation is a point where f(x) = 0 ; while substitution f(x) = x ˙ is used and x&*#x00A0;is a fixed point Nullclines are the curves where either x ˙ = 0 or y ˙ = 0 . They show whether the flow is completely vertical or horizontal. Vector fields in this aspect represent the direction of flow and whether flow is going away from fixed point or coming towards it. Phase portraits represent the trajectories of the system with respect to the parameters and give qualitative idea about evolution of the system, its fixed points, whether they will attract or repel the flow etc.
