At http://w3.pppl.gov/~hongqin/computerAlgebra.htm you will find reference to
a Symbolic Vector Analysis package developed by Hong Qin. I have made a
few minor changes to his Package (correcting some formatting bugs) and
put his Package, Notebooks, and PDF files at
http://www.physics.uwa.edu.au/pub/Mathematica/Calculus/
I suggest putting GeneralVectorAnalysis.m into a folder called Calculus
in the directory returned by evaluating $UserAddOnsDirectory.
Cheers,
Paul
