hey, In my physics class we are now learinging beginging to learn about lagrange ion mechanics and I am a little stuck on the basics of it particularly fermat's principle (dealing with light travel) and applications of the Euler-Lagrange Equation, I can't seem to get many of the problems at the end of the chapter, does anyone know a website or something that has a few worked out examples on how to do these?
thanks
thanks
