If a vector ﬁeld F can be written in the form ∇f for some scalar ﬁeld f, then we call F a gradient ﬁeld, or a conservative ﬁeld. The identity df/dt = ∇f · v is about a function in variable t. Thus ∇f should be

WebVector fields let you visualize a function with a two-dimensional input and a two-dimensional output. You end up with, well, a field of vectors sitting at various points in … Mathematically, a scalar field on a region U is a real or complex-valued function or distribution on U. The region U may be a set in some Euclidean space, Minkowski space, or more generally a subset of a manifold, and it is typical in mathematics to impose further conditions on the field, such that it be continuous or often continuously differentiable to some order. A scalar field is a tensor field of order zero, and the term "scalar field" may be used to distinguish a function of this kind with a m… polyps definition biology

Web3. @Mi-leeWilson You have to differentiate between the domain of definition of the field and the codomain. Both the vector field and the scalar field can have the same domain, e.g., (R^2) as in your example. But, a scalar field has (R) as codomain whereas a vector field has (R^n) with (n>1) as codomain. The vector field maps points to vectors ... WebLet (r) be an arbitrary scalar function. A magnetic field which satisfies B = B is called force-free because the Lorentz force density j(r) B(r) vanishes everywhere. There is some evidence that fields of this sort exist in the Suns magnetic environment.(a) Under what conditions is the sum of two force-free fields itself force-free?(b) Let (r) =
