[4 marks] Find the standard matrix, kernel and range of T . Let e i denote the i th column of the n n identity matrix. Then the standard matrix of T is A = T ( e 1 ) T ( e n ) = 1 1 1 1 1 . . . . . . . . . . . . . . . . . . . . . 1 1 1 1 1 1 . This matrix is invertible. Taking the determinant along the 1 st column, we get det A = det 1 1 1 . . . . . . . . . . . . . . . . . . 1 1 1 1 1 + (- 1) n +1 det 1 1 1 ....
