I've found a document that does some calculations related to LRL vector operator.
Somewhere in it, the author uses the equation below:
##{\Large \mathbf{L} \cdot \frac{\mathbf{x}}{r}=\frac{1}{r}(\mathbf{L} \cdot \mathbf{x})+\mathbf{x} \cdot (\mathbf{L} \frac{1}{r})+\frac{1}{r} (\mathbf{x} \cdot \mathbf{L}) }##
But I don't know how he got this. I can't prove it. This is really annoying me. Can anyone help?
Thanks
