The invariance of Lagrange's equations with a given "time"
What is the change in the Lagrangian in order that the Lagrangian equations of motion retain their form under the transformation to new coordinates and "time" give by:
q = q(Q, [tex]\tau[/tex])
t = t(Q, [tex]\tau[/tex])
The Lagrange equations of motion.
*That tau is not supposed to be a superscript of anything. I tried to write the LaTex code myself and it didn't work. It's just supposed to be regular lower case tau.
I have shown that the Lagrange equations of motion are invariant under a coordinate transformation of the same time, but I can't get this one to workout because I don't know how far I need to take the partials.
