Homework Statement
a) Find a mechanical system that is approximately governed by [itex]\dot{x}=sin(x)[/itex]
b) Using your physical intuition, explain why it now becomes obvious that x*=0 is an unstable fixed point and x*=[itex]\pi[/itex] is stable.
Homework Equations
[itex]\dot{x}=sin(x)[/itex] (?)
The Attempt at a Solution
I'm thinking a pendulum can be used as a mechanical system that varies with sinθ, but I'm not sure how to solidify my answer.
Could it possibly be an inverted pendulum in a very viscous medium?
