Extracted text: Which of the following is/are true about the least square method? ]Interchanging rows never changes the solution of the least square method. ]We need least square method to find an approximate solution of an inconsistent system. ]The least squares solution makes the error as small as possible. OWe should apply the least squares method to the system Ax=b, where b lies in the column space of A. Submit You have used 0 of 1 attempt Save
