Improper use of [nabla operator] in vector analysis

Obviously you have no idea what you are talking about. Let me show you...

Ooh, boy, now there's a red rag to a bull. You want to be careful saying things like that. At least this isn't sci.math where you would be ripped to shreds (and rightly so).

OK, I am sorry arildno. I shouldn't have said that (I guess I am getting too cocky these days). I apologize.

What is sci.math?

No hard feelings.

sci.math is an usenet news group, the original, if you will.

I would like to emphasize that this manipulative trick has nothing whatsoever to do with a proof of how the curl or div should look like when written in coordinate form.
Rather, it is a calculation device that brings out the correct formulae.

So does this manipulative trick works for any curvilinear coordinate system?

Just do a change of variable argument in precisely the same way.
