I made several assumptions and there's one that I made that isn't correct but I don't understand why. My textbook lists an...
I was wondering if anyone has any good resources for differential equations? I've been using Paul's Notes all semester but they don't cover the last chapter of my book. The chapter is Nonlinear Differential Equations and Stability. The topics are The Phase Plane: Linear Systems, Autonomous...
