Thanks BvU. I should have mentioned I have the third edition. The problem shows in this book exactly as I wrote it. I guess I'm stuck on the first part of the problem. I don't know how to interpret equation of motion from the lagrangian without solving the differential equation, and the equation...

Homework Statement In certain situations, particularly one-dimensional systems, it is possible to incorporate frictional effects without introducing the dissipation function. As an example, find the equations of motion for the lagrangian ##L = e^{γt} (\frac{m\dot{q}^2}{2} - \frac{kq^2}{2})##...
