Consider the following statements about the del operator.
1. The curl of a gradient is zero 2. The divergence of a curl is zero 3. The gradient of a divergence is zero
Answer: C
The first two are genuine identities and both are used constantly in field theory. The third is not an identity at all: the gradient of a divergence is a perfectly good non-zero vector, and it appears in the expansion of the curl of a curl.
