เฉลยข้อสอบมทริกซ์ ตอนที่ 2K'Keng Hale's1. The determinant of a zero matrix is 0. The transpose of a matrix P is equal to the transpose of PT.
2. Solving a system of linear equations by calculating the determinants of the coefficient matrices results in solutions for w=4, x=4, y=2, z=0.
3. The inverse of a non-singular matrix A is equal to the adjugate of A divided by the determinant of A.
เฉลยข้อสอบมทริกซ์ ตอนที่ 1K'Keng Hale's1. The determinants of matrices A, B, and C are calculated. The determinant of ABC is equal to the determinant of CBA.
2. The determinant of the matrix AB is calculated. When the dimensions of A and B are multiplied, the determinant is the product of the determinants.
3. A system of linear equations is solved using determinants and Cramer's rule. The solutions are found to be x=0, y=1, z=2.
