Let T: Rn → Rn be defined by T(→x) = A(→x) where A is an invertible n × n matrix. Then T is an isomorphism. Solution. The reason for this is that, since A is invertible, the only vector it sends to →0 is the zero vector. Hence if A(→x) = A(→y), then A(→x − →y) = →0 and so →x = →y. the ups store addison il
