What do you do when time is present in Lagragian Equation?

  1. Nov 26, 2006 #1
    I set up a Lagragian equation that involves time t. What do I do? I only know how to solve Lagragian equation in the absence of time. Please help.

    I understand the throw away, but when I differentiate

    dL/dq - d/dt (dL/dq dot) = 0

    do I care about time at all?

    If your (dL/dq dot) is a function of time, then why would you not care? I think once you have the simplified Lagarangian you do what you always do. It's been a long time since I did this stuff, but I don't see any reason to deviate from the example.
