Formula of the gradient of vector dot product
$begingroup$
On Wikipedia in the article "Vector calculus identities"
(https://en.m.wikipedia.org/wiki/Vector_calculus_identities)
there are the following two formulas for computing the gradient of vector dot product:
$nabla (A cdot B ) = (A cdot nabla) B + (B cdot nabla) A + A times (nabla times B) + B times (nabla times A)$
$nabla (A cdot B) = nabla A cdot B + nabla B cdot A$
Could you please explain what is the difference between terms $nabla A cdot B$ and $(B cdot nabla ) A$?
