Determinant of 3x2
WebThe determinant of a 2 x 2 matrix A, is defined as NOTE Notice that matrices are enclosed with square brackets, while determinants are denoted with vertical bars. Also, the matrix is an array of numbers, but its … WebCalculate a determinant of the main (square) matrix. To find the 'i'th solution of the system of linear equations using Cramer's rule replace the 'i'th column of the main matrix by solution vector and calculate its determinant. Then divide this determinant by the main one - this is one part of the solution set, determined using Cramer's rule.
