WebSpecifically, if a i + b j is any vector in R 2, then if k 1 = ½ ( a + b) and k 2 = ½ ( a − b ). A space may have many different bases. For example, both { i, j } and { i + j, i − j } are bases for R 2. … Webon V will denote a vector space over F. Proposition 1. Every vector space has a unique additive identity. Proof. Suppose there are two additive identities 0 and 0′. Then 0 ′= 0+0 = 0, where the first equality holds since 0 is an identity and the second equality holds since 0′ is an identity. Hence 0 = 0′ proving that the additive ...
