    For functional


    Why isn't [tex]J(q_1,...,q_n;\dot{q}_1,...,\dot{q}_n;t)[/tex]?

    I had an answer for you, but the TeX system stumped me, and I was unable to write it out. Sorry about that.

    J is a functional, and not a function of the q's. It should be written as:
    J[q_1(t), \ldots, q_n(t)]
