• Lagrangian Mechanics: From the Principle of Least Action to the Euler-Lagrange EquationsFrom Hamilton's principle we derive the Euler-Lagrange equations, show that L = T - U reproduces Newton's laws, and prove covariance under any change of generalized coordinates.PhysicsMechanics: Classical and Analytical MechanicsUndergraduateAnalytical mechanicsPrinciple of least actionEuler-Lagrange equationsGeneralized coordinatesCalculus of variations~21 min
