Functional derivative

  1. Apr 22, 2012 #1
    Hi,

    I have a question about a functional derivative. When determining the condition that the functional derivative have a stationary value of 0, do I use a partial derivative or a regular derivative? I would really appreciate the help. Thank you!

    Could you be a little more specific what the functional is?
    Regardless, here is something that you may find helpful:
