WebCurl identity: ∇×(fA) = (∇f)×A + f(∇×A), where A is a vector field and f is a scalar function. These vector identities are important tools in many areas of mathematics, physics, and engineering, and they can be used to simplify calculations and derive new relationships. WebSome of the other properties of div and curl are mentioned in the exercises for the section. First of all, they’re both linear. If k is a scalar, and F and G are vector elds, then div (kF) = kdiv F div (F G) = div F div G curl (kF) = kcurl F curl (F G) = curl F curl G Some version of the product rule also works for them.
