WebThe determinant of an n x n square matrix A, denoted A or det (A) is a value that can be calculated from a square matrix. The determinant of a matrix has various applications in the field of mathematics including use with systems of linear equations, finding the inverse of a matrix, and calculus. WebC inverse is equal to 1 over the determinant, so it's equal to 1/23, times the adjugate of C. And so this is going to be equal to 1/23 times the transpose of our cofactor matrix. So we …
