How does one distinguish a parametric scalar function from a vector function in the VectorCalculus package? Is SurfaceInt complete? Why is it necessary to provide a list of variables to integrate over in the declaration of the surface if I have already declared that I am trying to conduct business (as it were) in a different coordinate system. I am sure this package can be quite useful but I have to understand a little better what the limitations are in using it. I can't find any examples beyond the simplest possible in the help file.
I will be moving on to Flux soon. Since the engine behind these calculators must be similar I will see if I encounter the same roadblocks.
