Applications of Euler-Lagrange Equation

Click For Summary
SUMMARY

The discussion centers on the applications of the Euler-Lagrange Equation within the context of Lagrangian mechanics, particularly in relation to Fermat's principle of least time. Users recommend the Schaum's Outline series on Lagrangian Dynamics as a valuable resource for worked examples and problem-solving techniques. Engaging with these examples is emphasized as the most effective method for mastering the concepts. The conversation highlights the importance of self-practice in understanding complex physics topics.

PREREQUISITES
  • Understanding of Lagrangian mechanics
  • Familiarity with Fermat's principle of least time
  • Basic knowledge of calculus and variational principles
  • Access to Schaum's Outline series on Lagrangian Dynamics
NEXT STEPS

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

If you are looking for example problems, I would say the best source other than online sources I don't know of would be the Schaums series on Lagrangian Dynamics. They cover many different examples. Of course the best way to learn is to do them yourself!

Good luck.
