5015TRunnerSynchronize
13 Jan 2020  Modeling Scenarios  Contributor(s): Eli E Goldwyn
In this modeling scenario we practice finding and classifying equilibria of a onevariable differential equation. We do this in the context of a phase model which is often a simpler way of studying oscillatory phenomena. The idea is that instead of describing these oscillatory systems with...

13 Jan 2020  Modeling Scenarios  Contributor(s): Eli E Goldwyn
The goal is for students to practice finding and classifying equilibria of a onevariable system in this modeling context while also introducing variables defined on a restricted domain (the circle).
