Showing a system is invariant

  1. Mar 4, 2012 #1
    1. The problem statement, all variables and given/known data
    Show that I = log(u)-u+2log(v)-v is an invariant of the following system


    2. Relevant equations

    3. The attempt at a solution
    The question was given on a homework assignment, but I have very little idea what it is asking for and even less of an idea of how to solve it.
