In an autonomous system of two differential equations They can be defined as [2, 3]: 1. x-nullcline: The set of points in the phase plane where dx/dt = 0. Geometrically, the vectors at these points are vertical (straight up and down). You can find the x-nullclines by solving f(x, y) = 0. 2. y-nullcline: The set of points in … See more Nullclines are very useful for analyzing and sketching phase planes.
