For example, the vectors are linearly independent but not orthogonal. O O C False. For example, in every linearly independent set of two vectors in R. one vector...
Proofs are not necessary Exercise 6.8.12. Determine if the following statements are true or false. If a statement is true, prove it. If a statement is false, give a counterexample or some other proof showing it is false. Unless otherwise specified, let V and W be a finite-dimensional vector space over field F, let (v1, ..., Un} be a basis of V, let {1,...,n} be a subset of W (possibly with repeated vectors), and let 6: V W be the...
