Proving the curl of a gradient is zero - Mathematics Stack Exchange

WebMain article: Divergence. In Cartesian coordinates, the divergence of a continuously differentiable vector field is the scalar-valued function: As the name implies the divergence is a measure of how much vectors are diverging. The divergence of a tensor field of non-zero order k is written as , a contraction to a tensor field of order k − 1. Web∇ × ( ∇ f) = 0 using index notation. I have started with: ( e i ^ ∂ i) × ( e j ^ ∂ j f) = ∂ i ∂ j f ( e i ^ × e j ^) = ϵ i j k ( ∂ i ∂ j f) e k ^ I know I have to use the fact that ∂ i ∂ j = ∂ j ∂ i but I'm not sure how to proceed. vectors vector-analysis index-notation Share Cite Follow asked Oct 10, 2024 at 21:56 Ayumu Kasugano 355 2 9 crypto miner software reddit https://puremetalsdirect.com
