This morning I had 20 minutes before leaving for a class that I wanted to show a derivation of the equation of a tangent plane at a generic point in order to derive a property of the tangent plane as a function of position, and the dreaded overbar came into my formula from the palette dot product, so finally after years of not trying to find a work around I called tech support since I was out of time and was informed that by using either Student[LinearAlgebra] or VectorCalculus, this would not occur since it assumes variables are real! I had only loaded LinearAlgebra, and I had always thought Student just had the extra tutorials and a few less commands like the elementary row operation commands compared to the full package, but NO. Finally I learned the simple answer. I should have known Robert would have the answer. Thanks, Robert.
