I mean that the numerical solution like the attachment paper.

I have a second order nonlinear ODE. I know that a trajectory with specified initial conditions \left[ x(0) = x_0, \dot{x}(0) = \dot{x}_0 \right] is periodic. How can I numerically calculate period of this trajectory without solve this DE?

I found the answer on my question at http://en.wikipedia.org/wiki/Angular_velocity" : But W is not a tensor, W is a pseudotensor: W_{ij} = e_{iwj} \omega_{w}.

Hello. Sorry for my English There are R - rotation matrix (that performs transformation from associated coordinate system IE to static coordinate system OI) and \omega - angular velocity. The matrix R depends on parameters \xi (for example, Euler angles). I need to express \omega as function...
