Vector Identities: Calculate \nabla \cdot (f \nabla \times (f F))

[Monster007]

Vector Identities ??

Having heaps of trouble with v.identities any help possible would be greatly appreciated.

Let F = (z,y,-x) and f = |F| <--- (magnitude F)

Use vector identities to calculate;


_{\nabla \cdot (f \nabla \times (f F))}

GET THE book : VECTOR ANALYSIS and an introduction to TENSOR ANALYSIS by

MURRAY R. SPIEGEL in SCHAUM'S OUTLINE SERIES

IT is very good in this kind of vector identities
