Lagrangian and the Euler Lagrange equation

Click For Summary
SUMMARY

The discussion centers on the Euler Lagrange equation and its significance within Lagrangian mechanics. Participants recommend Richard Feynman's lectures, specifically the one found at Feynman Lectures on Physics, Volume II, Chapter 19, as a valuable resource for understanding these concepts. The importance of the Lagrangian is emphasized, particularly in its application to classical mechanics. Overall, the conversation highlights the need for foundational knowledge in Lagrangian mechanics to grasp the Euler Lagrange equation effectively.

TL;DR
I don't understand why the Euler Lagrange equation holds true.
I am new to Lagrangian mechanics and I am unable to comprehend why the Euler Lagrange equation works, and also what really is the significance of the lagrangian.
