WebIn algebra, Lagrange's identity, named after Joseph Louis Lagrange, is: which applies to any two sets {a 1, a 2, . . ., a n} and {b 1, b 2, . . ., b n} of real or complex numbers (or more generally, elements of a commutative ring).This identity is a special form of the Binet–Cauchy identity. In a more compact vector notation, Lagrange's identity is … WebJan 23, 2015 · 12. When you sum the terms in the diagonal you don't get. ∑ i = 1 n a i 2 ∑ j = 1 n b j 2. Instead, what you get is. ∑ i = 1 n a i b i 2. Let's write [ n] = { 1, …, n }. …
