This is an unwieldy definition, so we frequently use the equivalent statement
 +
 +
<math>\nabla \cdot \vec{F} = \frac{\partial f_1}{\partial x} + \frac{\partial f_2}{\partial y} + \frac{\partial f_3}{\partial z}</math>
 +
 +
or in two dimensions, just
 +
 +
<math>\nabla \cdot \vec{F} = \frac{\partial f_1}{\partial x} + \frac{\partial f_2}{\partial y}</math>.
