WebMar 3, 2016 · Technically operators are functions. When I first learned about them, functions are anything that takes in something and outputs an unambiguous something … WebAs H, G have the same curl, it follows merely that (G − H) is the gradient of some function. On that note, if you have a curl-free field W = (W1, W2, W3), it is the gradient of a function f given by f(x, y, z) = ∫1 0 (xW1(tx, ty, tz) + yW2(tx, ty, tz) + zW3(tx, ty, tz))dt.

Web"Curl is simply the circulation per unit area, circulation density, or rate of rotation (amount of twisting at a single point). Imagine shrinking your whirlpool down smaller and smaller … WebIn other words, it is a function. It's domain is (R x R) (where R is a set of real numbers), and its' codomain is R. (you take two real numbers and obtain a result, one real number) You can write it like this: + (5,3)=8. It's a familiar function notation, like f (x,y), but we have a symbol + instead of f.
WebJan 18, 2015 · For a vector field A, the curl of the curl is defined by ∇ × (∇ × A) = ∇(∇ ⋅ A) − ∇2A where ∇ is the usual del operator and ∇2 is the vector Laplacian.
