WebThe divergence of the vector field, F, is a scalar-valued vector geometrically defined by the equation shown below. div F ( x, y, z) = lim Δ V → 0 ∮ A ⋅ d S Δ V For this geometric definition, S represents a sphere that is centered at ( x, y, z) that is oriented outward. As Δ V → 0, the sphere becomes smaller and contracts towards ( x, y, z).
