I am in need of Noether's paper she wrote in around 1915 about variational symmetries.(adsbygoogle = window.adsbygoogle || []).push({});

I need to know how she found that [for an ode L(x,y,y')]if an X and Y (infinitesimals) exists then you can rewrite the Euler-Lagrange Equation in terms of L(x,y,y'), X(x,y) and Y(x,y).

This is really amazing how she didn't this. So instead of solving for y(x) in the E-L equ you can just plug it in to the equation she came up with.

If anyone could find the paper she wrote that would be awesome!!

Thanks
