Webcylindrical system by noticing that the ^zdz and ^ad vectors are perpendicular, so dA~ = ^ad ^zdz = ad dz^r Obviously the magnitude is dA = ad dz Likewise in spherical coordinates we nd dA~ from dA~ = a˚^sin d˚ a ^d = a2 sin d˚d ^r In spherical coordinates the magnitude is dA = a2 sin d˚d Patrick K. Schelling Introduction to Theoretical Methods WebTheorem 16.9.1 (Divergence Theorem) Under suitable conditions, if E is a region of three dimensional space and D is its boundary surface, oriented outward, then. ∫ ∫ D F ⋅ N d S = ∫ ∫ ∫ E ∇ ⋅ F d V. Proof. Again this theorem is too difficult to prove here, but a special case is easier. In the proof of a special case of Green's ...
