Example 2.7.3: the standard basis of rn. one shows exactly as in the above example 2.7.1 that the standard coordinate vectors. e1 = (1 0 ⋮ 0 0), e2 = (0 1 ⋮ 0 0), ⋯, en − 1 = (0 0 ⋮ 1 0), en = (0 0 ⋮ 0 1) form a basis for rn. this is sometimes known as the standard basis. in particular, rn has dimension n. Step 1: for e2 = (0, 1), we first find the coordinates of e2 in terms of the basis b. towards this end, we have to solve the system [0 1] = α1[− 1 − 3] α2[− 3 − 10]. doing so gives: α1 = 3, α2 = − 1 the coordinate vector of e2 with respect to b is [3 − 1]. note we could have done this differently: the coordinate vector [α1. Theorem 4.10.1: linear independence as a linear combination. let {→u1, ⋯, →uk} be a collection of vectors in rn. then the following are equivalent: it is linearly independent, that is whenever k ∑ i = 1ai→ui = →0 it follows that each coefficient ai = 0.
