Linear Algebra Definitions Questions and Answers 2023. linear transformation Correct Answers: (from a vector space V into a vector space W): A rule T that assigns to each vector x in V a unique vector T(x) in W such that (i) T (u+v) = T(u) + T(v) (ii) T(cu) = cT(u) for all u in V and all scalars c standard matrix Correct Answers: for a linear transformation T: R^n -> R^m, there exists a unique matrix A such that T(x) = Ax for all x in R^n. This is called the standard matrix. A = [...
