Mathematical Function Use in ODEs???

Does anyone know if it is possible to use named functions (e.g. sine) in the ODE "evolution"?
[I want to simulate a "particle on a hoop" under the influence of a separate external force field.]

Yes. For example if you want to say that dx/dt is sin(w*t), your command should read
dx/dt=Math.sin(w*t)
Hope it helps.

The OSP parser within EJS can be used used to compute the ODE rate. See how this is done in the Barrier Scattering model.
