I can already tell this semester is going to be a rough one. With two weeks until the semester begins, I've been attempting to work through the notes for my classical mechanics course (lagrangian & hamiltonian mechanics). Wow. Really dense stuff. I'm having a pretty difficult time following the concepts, and the textbook they've prescribed cannot be found anywhere. So, I've started this thread for two reasons: 1) Could anyone recommend a decent introductory classical mechanics textbook(s)? 2) I'd like to hear your experiences with classical mechanics. Is it really a difficult course? Any study tips you could share?
