Homework Statement

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 .
