Find Symmetry for Lagrangian in 3D Cylindrical Coordinates

AI Thread Summary
The discussion revolves around finding a symmetry for the Lagrangian of a particle in three-dimensional cylindrical coordinates, where the potential energy is a function of r and kθ + z. The original poster is seeking assistance but is reminded that they should follow the forum's homework guidelines by stating the problem clearly, providing relevant formulas, and showing their attempts at a solution. There is a request for clarification on the variable k, which is suggested to be a constant. The conversation emphasizes the importance of demonstrating work to receive help effectively.

the question is that there is a particle in 3 spatial Euclidean dimensions in cylindrical coordinates.
I want to find a symmetry for the lagrangian if the potential energy is function of r and k.theta+z
V=V(r,k.theta+z)
any help please ?

Welcome to PF!

This looks like a homework problem. PF has a template for homework problems where you state the problem, show us relevant formulas needed to solve it and then your attempt to solve it. We can't help you if you don't show any work first.

In your problem what is k? Is it some constant?
 
ok thanks I am new here
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
