Homework Help: Hamilton-Jacobi Equation

  1. Aug 17, 2010 #1
    1. The problem statement, all variables and given/known data

    Using the Hamilton-Jacobi equation find the trajectory and the motion of a particle in the
    potential [tex]U(r)=-Fx [/tex]

    2. Relevant equations

    Hamilton-Jacobi Equation: [tex]\frac{\partial S}{\partial t}+H(q_1,...,q_s;\frac{\partial S}{\partial q_1},...,\frac{\partial S}{\partial q_s};t)=0[/tex]

    3. The attempt at a solution

    From HJE, since y and z are cyclic,

    All this is grand, but the next step in the solutions I have say that we can now say that [tex]

    I don't see where this comes from.

    Any ideas?
