Well I guess I'm not sure exactly how one would go about doing what you suggest.
I recognize the steps that I saw in the derivation for a Lagrangian that is invariant under the said transformation, soI think I understand the idea, but I'm definitely missing something...does anyone know where...
I've been trying to solve the problem of deriving the conserved "Noether Charge" associated with a transformation q(t) --> Q(s,t) under which the Lagrangian transforms in the following way:
L--> L + df(q,t,s)/dt (i.e. a full time derivative that doesn't depend on dq/dt)
I am guessing I...
