Gradient and curl
WebJul 4, 2024 · The gradient is the vector dual to the linear map on vectors given by the directional derivative of a function, (∇f(x)) ⋅ v = dfx(v) = d dt t = 0f(x + tv). The advantage of this definition is that is independent of any particular coordinate system. WebCite this chapter. Matthews, P.C. (1998). Gradient, Divergence and Curl. In: Vector Calculus.
