Deriving Wave Equation by Vector Approach

  1. Jul 27, 2009 #1
    Hi there,
    i would like everyone to evaluate my working here,
    this is my attempt to wave equation / vibrating system using vector approach.
    please correct me if i had made some mistakes.


    Your help is much appreciated,
    Thanks, and have a nice day. :smile:


    Regards,
    Daniel.

    I didn't know that we can compute the Laplacian of a vector.
    [tex]\nabla^2 \vec{U}[/tex] :confused:

    erm sorry i don't quite understand your question,
    why is it not?

    and thanks for looking at my work =)

    i think i got what you mean,
    position vector is considered as scalar field as well, isn't it?
    it is just a notation of denoting the field.
