7.7 Determinants. Cramer’s Rule - ppt download: For n = 1, this determinant is defined by (2) D = a Determinants. Cramer’s Rule A determinant of order n is a scalar associated with an n × n (hence square!) matrix A = [ajk], and is denoted by (1) For n = 1, this determinant is defined by (2) D = a11.
