%%This entry should be written in a way that mirrors the page, [Hamiltonian mechanics.](Hamiltonian%20mechanics.md) The same principles are mirrored except Lagrangian mechanics uses different equation of motion.%% %%What sort of object is a lagrangian? It's not really an observable in the same sense as the Hamiltonian is a classical observable.%% #Mechanics #Mechanics/MathematicalFoundations
