Curl math definition

WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point. WebMay 28, 2016 · The curl of a vector field measures infinitesimal rotation. Rotations happen in a plane! The plane has a normal vector, and that's where we get the resulting vector field. So we have the following operation: vector field → planes of rotation → normal vector field. This two-step procedure relies critically on having three dimensions.
