"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 " - How to sketch scalar field
