## Homework Statement

Derive the 2 divergence equations from the 2 curl equations and the equation of continuity.

## Homework Equations

∇°D=ρ

∇°B = 0

∇xE = -∂B/∂t

∇xH = J + ∂D/∂t

∇°J = -∂ρ/∂t (equation of continuity)

## The Attempt at a Solution

1)∇xE = -∂B/∂t

∇°(∇xE) = ∇°(-∂B/∂t)

0 =∇°(-∂B/∂t) (divergence of curl of vector field is 0)

I'm stuck now I don't know what to do

2)∇xH = J + ∂D/∂t

∇°(∇xH) = ∇°(J + ∂D/∂t)

0 =-∂ρ/∂t + ∇°∂D/∂t

Once again I am stuck here too

Please guide me guys
