Chapter 4. Lagrangian Dynamics
Hamilton’s Principle, from which the equations of motion will be derived. These equations are called Lagrange’s equations. Although the method based on Hamilton’s Principle does not constitute in itself a new physical theory, it is probably justified to say that it is more fundamental that Newton’s equations.
