A synonym for null space is kernel. c) The rank-nullity theorem says that, if B is an m n matrix, then dim R ( B) + dim N ( B) = n. Let A be m n and apply the rank nullity theorem to A and A T A : n = dim R ( A) + dim N ( A) n = dim R ( A T A) + dim N ( A T A) Since by part b we have dim N ( A) = dim N ( A T A), we conclude dim R ( A) = dim R ( A T A).
