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. WebHere, you think of this 2d curl, as like an operator, you give it a function, a vector field function, and it gives you another function, which in this case will be scalar valued. And …
