    That makes no sense at all. I could guess that p and q are "generalized coordinates" and that L is the Lagrangian (so this is a physics problem, not a math problem) but I have no idea what you want to solve for!

    You will find the derivation in any textbook devoted to Classical Mechanics. I suggest you spend some time in the appropriate library of the institute you study at.

    thanks
    I did not find this proof in the curriculum, but this question got a zero ...
    I proved H=T+V
    Where  L=T-V and \sum_i p_i {\dot q_i}=2T

    ... No problem thank you again
