WebThe Greens reciprocity theorem is usually proved by using the Greens second identity. Why don't we prove it in the following "direct" way, which sounds more intuitive: ∫ all space ρ ( r) Φ ′ ( r) d V = ∫ all space ρ ( r) ( ∫ all space ρ ′ ( r ′) r − r ′ d V ′) d V = ∫ all space ρ ′ ( r ′) ( ∫ all space ρ ( r) r ′ − r d V) d V ′ on the younger arc of the caribbean islands
