Analytical Mechanics, Lesson 2: D' Alembert's Principal and Lagrange's Equations of Motion

[TradingTutor]

Damn, these 1-2 minutes videos about analytical mechanics you post have much more information and explain much better than my 1 hour classes and Goldstein's book combined. Very nice :)

And of course, all taken from Goldstein

it is impressive that people actually derived such results. im about to start first year in university know DE lots of calculus (multi, single) series etc etc... and i cannot understand a thing beyond the start. He on the other hand managed to do this so many years ago and he knew he was getting somewhere and not just writting nonsence

[BarriosGroupie]

@h0wud0in2 he doesn't understand what he's doing. He's just regurgitating it from a book.

[h0wud0in2]

@BarriosGroupie no i meant Lagrange

[BarriosGroupie]

@h0wud0in2 haha! yeah Lagrange was amazing. He created generalized coordinates, lagrange multipliers etc.
