We were working on some Lagrangian and trying to solve it using an ansatz. Due to some problems in the results we got, we started to doubt the correctness of the method in use. Here is a very simple Lagrangian which shows the problem very easily: L=\frac{1}{2}\dot{x}^{2}-gx We took m=1 for the...

Yes, this gives the exact same solution.
