Tricky Laplace

Hi.


But I am concerned it does not answer the question, can anyone help in this regard please?

It is not of the same form, I think I have proved the general term, but not what the question has stated fully :/

As you are definitely the expert on vector calculus on here, I wondered if I could check something with you?

Nothing wrong with this approach.

From a teaching point of view, most universities rarely cover grad/div/curl derivations in other coordinate systems and therefore the method you suggest is not seen/taught.To be fair, Cambridge went straight (in the 1st term!) to general curvilinear coordinate derivations, including some pretty confusing discussion of contra/covarient values which I think left most of us feeling very unsure of our footings in this area. Once we realised that in the exams it would only ever be cylindrical/spherical life became somewhat easier!

Oh! Those were the days...I still feel the pain now.

Though part of me is disappointed at never having actually solved a problem involving, say, prolate spheroidal coordinates.

A very small part of me, to be clear...
