,’s Integral and ,’s Second Form of Dynamical Equations,one can derive the differential equations of motion in a still simpler way than from the principle of least action. It appears that this principle had not been noticed earlier, because here in general one does not obtain a minimum with the vanishing of the variation, as it happens in the case of the
