## Homework Statement

f= scalar field

F = vector field

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

## 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)
