are these the only things that can be done to a Lagrangian such that the equations of motion have the same solutions q(t).

Thanks!!

There is a wider class of so called canonical transformations.

There is a wider class of so called canonical transformations.

These are the ones i'm having a problem with. the modified Hamilton's principle gives this definition for a canonical transformation:

pq - H = PQ - K + (total time derivative).. and that's because you can add a total time derivative inside the integral for the action.

I also want to know if there is more transformations on the Lagrangian without a change of variables.

Thanks :)
