Hi Simon No problem, links are great! Ok, thank you for the explanation and the link, which will be further investigated. Actually I wasn't thinking about a Poincare Section, which is far above my level. As far as I know, this requires finding the energy in the system, but I might be wrong...

Thank you. Soon I'll have two free weeks, where I am to write a paper about non-linear dynamics and chaos theory. With the level of education I have, I'm taking a illustrative route (with some comparing to fractals), but I thought I at least should find the equations of motions for the double...

Thank you Simon, I'ill look at it a bit later, right now I'm not at a pc with Mathematica. It looks perfect though, thank you! As you probably could see by my coding, I'm very new to Mathematica. I knew about the Euler-Lagrange method, but that's above my level in physics. I'm using this...

Hello Im new here, I hope I'm not disturbing anyone. Following this guide below, I am trying to find two 2. order differential equations, one for q1'' and one for q2'', describing the movement of the double pendulum. I have no problems with the mathematics, but when the guide tells me to...
