Okay, so I'm learning some basic index notation, and I have a few questions...(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

f= scalar field

F = vector field

so, we are supposed to show that curl(fF) = fcurl(F) + ([tex]\nabla[/tex]f) x F

3. The attempt at a solution

curl(fF) = [[tex]\nabla[/tex] x (fF))][tex]_{k}[/tex] = [tex]\in[/tex][tex]_{ijk}[/tex](f[tex]\partial[/tex][tex]_{i}[/tex]F[tex]_{j}[/tex] + F[tex]_{j}[/tex][tex]\partial[/tex][tex]_{i}[/tex]f)

any help??

(all the superscripts are supposed to be subscripts, i dunno)
