Notes Relativistic Lagrangian for a charged particle in electromagnetic field. The Lagrangian describes the dynamics of the system and is used in the Lagrangian formulation of classical mechanics to derive the equations of motion of the particle. The principle of ...
Notes Small oscillations Lagrangian approach is suitable for the system with small oscillation about an equilibrium position. The theory of small oscillation about equilibrium position is applicable in molecular spectra, …
