Could someone please direct me to a good web page or comment on the main difference between the euler lagrange eqn and lagranges eqn of motion. I'm struggling to differentiate between the two...

Also, I'm struggling to grasp the concept of Lagrange density - when does one introduce this into the action integral?

Cheers
