WebSuch a function describes a vector ﬁeld. Thus, by taking the gradient we convert a scalar ﬁeld to a vector ﬁeld. 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 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 ...
