Appreciate the fundamental concepts of vector calculus; the relations between line, surface and volume integrals. When a vector field represents force, the line integral of a vector field represents the work done by a force moving along a path, and, under this interpretation, conservation of energy is exhibited as a special case of the fundamental theorem of calculus.
