    Maybe classical chaos is still the frontier.

    A learn's puzzle on transformation equation

    I guess that t represents the change of the constraint with time. Is it right?

    A learn's puzzle on transformation equation

    Thanks very much for your reply! But how about the degrees of freedom? A system with n degrees of freedom just needs n independent coordinates. If adding t, there must be one coordinate(q1, q2,..., or t) which is dependent. :confused:

    A learn's puzzle on transformation equation

    Hi, I'm a new learner of CM and I was stuck at the very beginning. TT The transformation equation is ri=ri(q1,q2,...,qn,t) I wonder why t should be in the bracket. Aren't r determined by these independent coordinates？ Isn't t already contained in them?
