Description

This is an introductory course in Lagrangian mechanics provided for college students and anyone who is familiar with Newtonian mechanics and calculus. 

In this course you will learn how to apply Lagrangian mechanics to the classical systems and find their equations of motion and their physical quantities. When applied to the classical systems, Lagrangian mechanics is equivalent to the Newtonian mechanics, but more easier than it, especially when you are dealing with more complicated systems.

Register to this course and enjoy learning Lagrangian mechanics!

Who is the target audience?
