Green's first identity
WebGreen's identities are a set of three vector derivative/integral identities which can be derived starting with the vector derivative identities (1) and (2) where is the Divergence, is the Gradient, is the Laplacian, and is the Dot Product. From the Divergence Theorem , (3) Plugging (2) into ( 3 ), (4) This is Green's first identity.

The identity follows from the product rule. d d x ( f ( x) ⋅ g ( x)) = d f d x ( x) g ( x) + f ( x) d g d x ( x). for two functions f and g. Noting that ∇ ⋅ ∇ = Δ we get. ∇ u ⋅ …

Web2 Answers Sorted by: 1 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. Webwhich is Green's first identity. To derive Green's second identity, write Green's first identity again, with the roles of f and g exchanged, and then take the difference of the two equations.
