    Graduate Proof: curl curl f = grad (div (f)) - grad^2

    Anyone?

    Graduate Proof: curl curl f = grad (div (f)) - grad^2

    This is the result: î(δyδxF2 - δy²F1 - δz²F1 - δxδzF3) + j(δx²F2 - δxδyF1 - δzδyF3 - δz²F2) + k(δxδzF1 - δx² - δy²F3 - δyδzF2)

    Graduate Proof: curl curl f = grad (div (f)) - grad^2

    I got stuck doing this, I tried to use curl twice on the left side to see if It would show as the right side.. but couldn't.. Oh, thanks by the way! =)

    Graduate Proof: curl curl f = grad (div (f)) - grad^2

    Can anyone help me proving this: http://img88.imageshack.us/img88/3730/provei.jpg And just for curiosity, is there a proof for why is the Laplace operator is defined as the divergence (∇·) of the gradient (∇ƒ)? And why it doesn't work on vetorial function. Thanks in advance, guys! Igor.
