Web1 The sets f(x;y) = 0 and g(x;y) = 0 are curves on the phase portrait, and these curves are called nullclines. 2 The set f(x;y) = 0 is the x-nullcline, where the vector eld (f;g) is vertical. 3 The set g(x;y) = 0 is the y-nullcline, where the vector eld (f;g) is horizontal. 4 The nullclines divide the phase portraits into regions, and in each ...
