A Student's Guide to Lagrangians and Hamiltonians. . The Hamiltonian method. Hi, I've seen the words "Calculus of Variations" mentioned quite a bit but never thought too much about them since it seemed too advanced. Well, I am nearly finished the computational style calculus and am awaiting my Apostol text to get more into the theory but I also picked up a text called Calculus of Variations for like $5 (Second hand Dover book!. What's the point of Hamiltonian mechanics. 539.291.721.3.. Can we use lagrangian mechanics for solving fluid mechanics problems. most books on analytical mechanics Variational Calculus and Physics. Lagrangian and Hamiltonian mechanics.This is between mechanics and E&M, but you can include thermal and quantum physics if you want. Overall, I find mechanics easier than E&M. I enjoyed most of the mechanics topics except angular dynamics,. I'm trying to delve into self study of advanced th
