Hamiltonian Method

  1. Apr 4, 2015 #1
    Hey, I was hoping someone could clear this up for me. When using this method, how do you get the final equation of motion, that's where I am confused.

    So I know I start off using Lagrangian (T - U) -> momentum (partial L/ partial q dot) -> Hamiltonian T+U, and then using the hamiltonian equation's of motion, we find the equations ( I can do this part). This is just a quick summary of the procedure. But, for some examples, they are taking time derivatives at the end for some equations, and finding the equation of motion. I don't understand why and where they come from?
    Could someone please explain, thanks.
