- Divergence and curl are two important concepts in vector calculus. The divergence of a vector field measures the fluid flow “out of” or “into” a given point1. The curl indicates how much the fluid rotates or spins around a point1. Here are some examples of divergence and curl:
- Divergence of curl: ∇∇ ⋅ (∇∇ × F) = 0
- Curl of gradient: ∇∇ × (∇∇f) = 0
- Divergence of cross product: ∇∇ ⋅ (f{∇∇g × ∇∇h}) = ∇∇f ⋅ (∇∇g × ∇∇h)
- Divergence of difference: ∇∇ ⋅ (f∇∇g − g∇∇f) = f∇∇2g − g∇∇2f
- Curl of curl: ∇∇ × (∇∇ × F) = ∇∇(∇∇ ⋅ F) − ∇∇2F2.

Divergence and curl example - Math Insight
WEBExample. Calculate the divergence and curl of F = (−y, xy, z) F = ( − y, x y, z). Solution : Since. ∂F1 ∂x = 0, ∂F2 ∂y = x, ∂F3 ∂z = 1 ∂ F 1 ∂ x = 0, ∂ F 2 ∂ y = x, ∂ F 3 ∂ z = 1. we calculate that. divF = 0 + x + 1 = x + 1. div. .
