I was going to troll with this, and I wouldn't have ruined it by being so obvious. Go fuck yourself, unless this is a meta-troll meant to troll actual trolls, in which case well played.

That identity is great but your expression for it isn't as nice as the vector analysis one.

Is this a Mandala effect thread? I think Stokes' theorem says the integral of the divergence in a volume is equal to the integral of the curl on the volume's surface.

You mean, real mathematician's notation? Unlike what your unqualified calc teachers said, there's a time and a place to use $dx$ with $\int$ . It has an actual meaning.
