9. 6 determinants and cramer"s rule notes: sterling. Provide a generalization to each of the key terms listed in this section. The determinant of any 2 2 matrix can be showed as the following: The determinant of any 2 2 matrix, which is also called the 2 by 2 determinant of a can be also expressed as any of the following: det(a) The determinant of any 2 2 matrix, which is also called the 2 by 2 determinant of a can be also denoted as any of the following: det(a) = ad bc. 2 2 m atrix det(a) = a(d) b(c) 3 3 m atrix det(a) = b (f g di) + a (ei f h) + c (dh eg) = (aei + bf g + cdh) (gec + hf a + idb) det b e c a d f g h i. = a det(cid:18)e f h i(cid:19) b det(cid:18)d f i(cid:19) + c det(cid:18)d g h(cid:19) g e.
