Hello there,
I am dealing with the functional (http://en.wikipedia.org/wiki/First_variation)
J = integral of (y . dy/dx) dx
When trying to compute the Euler Lagrange eqaution I notice this reduces to a tautology, i.e.
dy/dx - dy/dx = 0
How could I proceed for finding the y(x) that effectively minimizes the functional?
Thank you very much
Yours
