From the Divergence Theorem , (3) Plugging (2) into ( 3 ), (4) This is Green's first identity. Web1 Probably you don't need Green's identity but similar idea as proof in Green's identity. The key technique is Divergence theorem. Consider identity: ∫ V ∇ ⋅ ( f ∇ f − f ∇ g) d V = ∫ V ( ∇ f ⋅ ∇ f + f Δ f − ∇ f ⋅ ∇ g − f Δ g) d V = ∫ V ∇ f ⋅ ( ∇ f − ∇ g) d V = ∮ ∂ V ( f ∇ f − f ∇ g) ⋅ d S = 0 The third line uses Δ f = Δ g = 0. phoenix fire helmets for sale
