Abstract

Acceleration terms in a lagrangian are sometimes eliminated by substituting into the lagrangian the equations of motion which were obtained from the lagrangian. We show that, in general this is an incorrect procedure. In addition, we present a new correct procedure, which we call the method of the double zero. © 1980, All rights reserved.
