WebApr 9, 2024 · Proof of Green's identity. calculus multivariable-calculus derivatives laplacian. 8,790. 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 ⋅ … 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.
