Do you mean I must express $T$ as a function of only $\dot{y}$? That seems to limit the method. Moreover, Lagrange equations could then be simplified using $\frac{\partial L}{\partial y}=\frac{\partial V}{\partial y}$ and $\frac{\partial L}{\partial \dot{y}}=\frac{\partial T}{\partial \dot{y}}$ | |
