I'm doing an assignment where the lecturer has said scalar fucntion g(x,y,z) = x^3 + y + z^2(adsbygoogle = window.adsbygoogle || []).push({});

and vector field F = (2xz,sin y,e^y)

and asked find

a) grad g

which is fairly easy, but then

b) div g

and my understanding was that you can only find the divergence of a vector field not a scalar function.

Am I right an theres been a typo and he meant div F, or can you actually find div g, Because theres no actually mention of F in any of the questions, which is odd.
