Web2. If JohnD has interpreted the problem correctly, then here's how you would work it using index notation. Here, i is an index running from 1 to 3 ( a1 might be the x-component of a, a2 the y-component, and so on). ∇ ⋅ (φa) = ∇i(φai) Since these are all components (not vectors), you can attack this with the product rule. WebProof for the curl of a curl of a vector field. Yes, there's a more elegant way! It uses the language of differential forms, which has replaced the 19th-century language of gradients, divergences, and curls in modern geometry. ...
