How do you determine the divergence of a vector?

Answer by  mathman112358 (12)

The divergence of a Vector Field is a scalar quantity, and it is a measure of how much the field 'splits' or 'converges' at given points. The quantity is given by the sum of the coordinates of the Gradient Vector, i.e. the partial derivatives of the field. Positive and negative values correspond to 'sources' and 'sinks' of the field.

A vector is a speed with a direction. Divergence is the distance away that something is from where it was expected to be. If you aim for the pocket corner in pool and you hit the bank 20 cm away, you have a divergence that can be figured out trigonometrically.
