How does $\dot{q}_i p_i - H = \dot{Q}_i P_i - K + \frac{d}{dt}F$ will give the same EL and E... [duplicate]
How does $\dot{q}_i p_i - H = \dot{Q}_i P_i - K + \frac{d}{dt}F$ give the same Euler-Lagrange equations and Equations of motion (EoM) for corresponding coordinates and allow us to determine a canonica …

After reading all the answers rigorously, I came up with a simple explanation. The Lagranian $L(q,\dot{q},t)$ has no notion of path, only of the values $q,\dot{q}$. At each instant "$t$", the values $ …
