How to derive lagrangian equation

WebMar 5, 2024 · There would be no harm done if you prefer to write Ek, Ep and E for kinetic, potential and total energy. I shall stick to T, U or V, and E. Now, instead of writing F = ma, we write, for each generalized coordinate, the Lagrangian equation (whose proof awaits a later chapter): [Math Processing Error] http://complex.gmu.edu/www-phys/phys705/notes/003%20Derivation%20of%20Lagrange%20equations%20from%20D%27Alembert.pdf
