WebJan 17, 2015 · Proof for the curl of a curl of a vector field. For a vector field A, the curl of the curl is defined by ∇ × (∇ × A) = ∇(∇ ⋅ A) − ∇2A where ∇ is the usual del operator and … WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.

The physical meaning of divergence can be understood as a measure of spreading out (diverging) of a vector at any point (space coordinates). Mathematically the divergence of a vector can be computed by taking a dot product of the vector with del () So if then the divergence of at any point (x,y,z) can be computed as:

WebCirculation plays an important role in vector calculus. Circulation defined by line integrals forms the basis for the “microscopic circulation” of the curl of a vector field . Three of the four fundamental theorems of vector calculus involve circulation.
