I have the equation(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\frac{d\rho}{dt}[/itex]=-[itex]\nabla[/itex][itex]\cdot[/itex][itex]\rho v[/itex]

where the vector v depends only x and t.

I want to take the partial derivative of this whole equation with respect to t.

Just not sure how to take the partial of the divergence. Thanks!
