    Lightbulb a problem!

    I need help with this question for my upcoming homework.

    Any help will be appreciated.



    Show that

    \bigtriangledown\cdot(\vec{v}\times\vec{w})=\vec{w }\cdot(\bigtriangledown\times\vec{v})-\vec{v}\cdot(\bigtriangledown\times\vec{w})<br />



    Thanks!

    What have you tried?

    P.S. \nabla \nabla...that'll save you some writing.
