WebJan 6, 2024 · Next, consider the product, dealing with three variables, given by (a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2ac + 2bc.To establish the equality, consider a square of sides a + b + c.Since the length of the sides is a + b + c, the area of the square is (a + b + c) 2.We will show that, this is equal to a 2 + b 2 + c 2 + 2ab + 2ac + 2bc.. Clearly, area of the square … 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 ′
