"WebTherefore, the unit normal vector at P can be used to approximate N(x,y,z) across the entire piece Sij, because the normal vector to a plane does not change as we move across the plane. The component of the vector ρv. at P in the direction of N is ρv·N. at P. Since Sij. is small, the dot product ρv·N. changes very little as we vary across Sij, " - Inward normal vector
