WebThe row space of A is the column space of A^T True (4.6) If B is any echelon form of A, and if B has three nonzero rows, then the first three rows of A form a basis for Row A False, see the warning after example 2 (4.6). The row operations will change the linear dependence relations among the rows of a matrix WebUse the fact that det (B) = det (B T) for all square matrices B and the fact that det (BC) = det (B) det (C) for all square matrices B and C (of the same size) to deduce that if A is orthogonal, then either det (A) = 1 or det (A) = − 1 (so the area scaling factor is always 1).
