initial and final conditions of q(t), i.e.
Thus, the path that extremizes the action is exactly that which solves the Euler-Lagrange equation, which is the classical path.
Thus, the correct solution to the classical equations of motion also extremizes the action.
The action principle is more than just a formal device.

What is the concept of Lagrangian?

La·grang·ian lə-ˈgrän-jē-ən -ˈgräⁿ-zhē- : a function that describes the state of a dynamic system in terms of position coordinates and their time derivatives and that is equal to the difference between the potential energy and kinetic energy compare hamiltonian.

What is Hamilton's principle of Lagrange equation?

For many systems, these equations are mathematically intractable.
Running the calculus of variations argument in reverse, we established Hamilton's principle: the system moves along the path through configuration space for which the action integral, with integrand the Lagrangian L=T−U, is a minimum.

What is the Lagrangian field theory?

Lagrangian field theory is a formalism in classical field theory.
It is the field-theoretic analogue of Lagrangian mechanics.
Lagrangian mechanics is used to analyze the motion of a system of discrete particles each with a finite number of degrees of freedom.
