Simple question about the gradient?

  1. Aug 23, 2010 #1
    1. The problem statement, all variables and given/known data
    When i see the upside down triangle squared .
    Is this the Gradient squared, or the second derivative of the x , y and z components
    And this is the Laplace operator

    It's the Laplace operator. It's not the gradient squared. It's the sum of the second derivatives.

    Ok thanks, so i take the second derivatives and then add them up .
