First, we have just seen that T(→v) = proj→u(→v) is linear. Therefore by Theorem 5.2.1, we can find a matrix A such that T(→x) = A→x. The columns of the matrix for T are defined above as T(→ei). It follows that T(→ei) = proj→u(→ei) gives the ith column of the desired matrix. earth day 2022 books https://lagycer.com
