Divergence of a vector formula
WebThe divergence of V = Vi∂i is determined by (divV)ω = d(V⌟ω) ≡ V(ω), hence we get: (divV)ω = [Vi∂i(√ det (g) ) + √ det (g) ∂iVi]dx1 ∧ … ∧ dxn, Where we used the obvious formula V(dx1 ∧ … ∧ dxn) = (∂iVi)dx1 ∧ … ∧ dxn. Therefore divV = 1 √ det (g) ∂ ∂xi[√ det (g) Vi] Edit added in reply to Asaf Shachar's comment WebMar 14, 2024 · This scalar derivative of a vector field is called the divergence.

WebThe divergence theorem-proof is given as follows: Assume that “S” be a closed surface and any line drawn parallel to coordinate axes cut S in almost two points. Let S 1 and S 2 be the surface at the top and bottom of S. These are represented by z=f (x,y)and z=ϕ (x,y) respectively. F → = F 1 i → + F 2 j → + F 3 k →. , then we have. WebDec 31, 2024 · Intution : The divergence of a three-dimensional vector field is the extent to which the vector field flow behaves like a source at a given point. But if my vector field is F = P, Q, R then formula is for divergence is given as P x + Q y + R z. I want to know how this formula capute that intutitve idea. I studied using MIT OCW.
