Let S be a subspace of R. (a) Write a definition for the orthogonal complement of S in R”. (b) Let A = 102 (193). 14 Find a basis for the orthogonal complement of the row space of A. (c) Let A be an arbitrary m × n matrix. Show that the orthogonal complement of the row space of A is the Nullspace of A. (d) Show that if S has dimension k, then the orthogonal complement of S in R" has dimen- sion nk (use part (c)).
