WebIn curvilinear coordinates, the basis vectors also depend on positions, so every time you differentiate a vector field, you need to make sure to take the variation of the basis vectors also into account, so we calculate the divergence as div(A) = ∑ i gi ⋅ ∂A ∂ui = ∑ ij gi(∂Aj ∂uigj + Aj∂gj ∂ui) = ∑ ij (∂Ai ∂ui + ΓijiAj). 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).
