1. The problem statement, all variables and given/known data [PLAIN]http://img411.imageshack.us/img411/4412/sssa.jpg [Broken] 2. Relevant equations 3. The attempt at a solution Actually I have very basic knowledge of university physics and math, so the only things I've done are calculating Hamilton equations (I hope correctly) q'=p2+p1 p'=-(q2+q1) and f3 as I guess it was poisson brackets f3=4q2p2-4q1p1 Now I don't have enough theoretical mechanics knowledge to move on, any help would be very welcome. Thanks!
