Hello and thank you for posting your question to Brainmass.

The solution is attached below in two files identical in content but differ in format (MS-word and pdf) so you can choose the more suitable one for your needs.

The Del operator is a vector operator. This means that it has three components (in three dimensional space) and it operates on a scalar function:

When applied to a scalar function this ...
