Divergence of a vector formula
WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs … WebMar 14, 2024 · This scalar derivative of a vector field is called the divergence. Note that the scalar product produces a scalar field which is invariant to rotation of the coordinate axes. The vector product of the del operator with another vector, is called the curl which is used extensively in physics. It can be written in the determinant form

WebThe divergence of a vector field is a measure of the "outgoingness" of the field at all points. If a point has positive divergence, then the fluid particles have a general tendency to leave that place (go away from it), while if a point has negative divergence, then the fluid particles tend to cluster and converge around that point. WebThe same equation written using this notation is. ⇀ ∇ × E = − 1 c∂B ∂t. The shortest way to write (and easiest way to remember) gradient, divergence and curl uses the symbol “ ⇀ …

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
