I took vector calculus from professors in the institute of technology and in the school of liberal arts. You got a BS or a BA in Math depending on which was your home. The professors from the institute of technology used diagrams and related concepts to mechanics and electromagnetics. The professor from liberal arts taught a purely abstract course without such aids, and it was far more difficult to understand. It was also far less useful for an electrical engineer. That said, I realize that if one is headed for an advanced degree in theoretical physics, communications theory, solid state physics, etc., then the more abstract course may be the better choice.
