I am solving a problem involving Lagrange Multipliers and calculus of variations and have the equation:
f_{x} - d/dy [f_{x'}]
the only thing I don't know how to do is the notation of [f_{x'}]. Is this the partial of f with respect to x prime? if so, I don't know how I can do that because x is not a function of anything so how can there be a derivative of it without it being 0. Any help?
