A question on calculus of variations

  1. Nov 2, 2013 #1
    1. The problem statement, all variables and given/known data

    δ (∂x'^μ/∂x^β)=0

    This equation is on my textbook. I don't quite understand. Where x'^μ is coordinate component.


    2. Relevant equations



    3. The attempt at a solution

    Is the transformation from [itex]x[/itex] to [itex]x'[/itex] given or what are your symbols supposed to mean?

    Yes. It's the transformation from [itex]x[/itex] to [itex]x'[/itex].
    δ is Variational symbol.

    Ok, you must define the meaning of [itex]x'[/itex] or give the complete variational problem. I don't know, what's meant by this symbol!
