Standard Bases The standard basis for R" is {(1,0,0,...,0), (0, 1, 0, & 0), (0,0,0....,0,1)). en These vectors are typically denoted as (e₁,e₂,en). (In R³ the standard basis is also denoted by (i.j, k}) kz The dimension of R" is n. mxn real matrices. The standard basis for Mm.n is 07 To 1 *** 1 0 00 0 0 0 0 00 ...

P is an infinite dimensional vector space, since for each integer k> 1, we can find a linearly independent set {1,...,x} with more than k elements. The standard basis for Pis
