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. WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point.
