Title: WW7 - related to problem 7
Post by: Sarah Dunning on November 28, 2014, 12:36:27 PM
What is a vertical (x-)nullcline equation and how do you find it?

What is a horizontal (y-)nullcline equation and how do you find it?

Using the nullclines how do you estimate trajectories in the phase plane?

From context: $x'=0$ or $y'=0$ respectively.
