Divergence of a scalar is a vector
In 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. As an example, consider air as it is heated or cooled. The velocity of the air at … WebBusiness Contact: [email protected] More free math videos on mathgotserved.com thanks :DIn this clip we go over how to find the gradient and of scalar...

WebDivergence and curl are two measurements of vector fields that are very useful in a variety of applications. Both are most easily understood by thinking of the vector field as … WebMar 23, 2013 · however, LHS is a scalar (since divergence of a vector is a scalar) 1st term of RHS is a scalar (divergence of T is a vector and its dot product with another vector is a scalar). 2nd term of RHS - there is a problem it is going to be a tensor, which is not correct. Obviously there is something wrong with my understanding. Can someone …
