12. 3 systems of linear equations - determinants 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.
