Hi. I have this exam in vector calculus tomorrow, but i'm having trouble sorting the following formula out. Could someone help me on the track or show me why this is an equality. Feels meaningsless to merely memorize the formula.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\nabla \times (\bar{u} \times \bar{v}) = (\bar{v} \cdot \nabla) \bar{u} - \bar{v} (\nabla \cdot \bar{u}) + \bar{u} (\nabla \cdot \bar{v}) - (\bar{u} \cdot \nabla) \bar{v}
