Lagrange Multipliers - Force of Constraint for a Pendulum

Finding the force of constraint for a swinging pendulum. In this case, I use Lagrange Multipliers - then I solve the differential equation numerically using python. Here is my python code. https://trinket.io/glowscript/f22680f6c9 Second Semester Classical Mechanics Playlist    • Classical Mechanics 2 Spring 2023   00:00 - Intro 02:41 - Finding kinetic energy 06:31 - Euler Lagrange equation 11:36 - Numerical solution 15:51 - Python 21:33 - Work Energy Check
