the Euler-Lagrange |
Problem gives you : a particle of mass m that moves in one dimension
such that it has Lagrangian
L=1/12 m^2 x^4 + m x^4 V(x) - V^2(x),
where V(x) is of course differentiable, and the question is to find
the equation of motion for x(t).
I know that I am supposed substitute it into the Euler-Lagrange
equation, however I don't see how to do it. Anybody can help?

Do you know what the Euler-Lagrange equations are?
If so....what exactly is your problem?
