Homework Statement
(A.∇)B
What does this mean and how do I go about trying to expand this (using cartesian components)?
Well, [itex]\displaystyle \vec{\text{A}}\cdot\vec{\nabla}=\text{A}_x\,\frac{ \partial}{\partial x}+\text{A}_y\,\frac{ \partial}{\partial y}+\text{A}_z\,\frac{ \partial}{\partial z}\ .Homework Statement

Of course. It was the order (A.∇) rather than (∇.A) that confused me but now I realize that these are obviously equivalent. Thanks
