WebDec 15, 2015 · You can determine whether a vector field can be written as the curl of another vector field (in ) by looking at it's divergence. Assume a vector field F can be written as the curl of another vector field, call it G. Then F = curl G. Take the divergence of F, and say div F ≠ 0. WebJul 23, 2004 · The divergence is basically the surface integral of a vector function out of an infinitesimally small box, or other small closed shape. We take the limit of this integral divided by the shape's volume, as the volume tends to zero. ... jk'n so basicly div is how much the vector function "diverges" in a small area, and curl is how much the vector ... picture frames with cricut https://ridgewoodinv.com
