WebTheorem 2.3.3. A square matrix A is invertible if and only if detA ̸= 0. In a sense, the theorem says that matrices with determinant 0 act like the number 0–they don’t have inverses. On the other hand, matrices with nonzero determinants act like all of the other real numbers–they do have inverses. WebIf \( B \) is a non-singular matrix and \( A \) is a square matrix, then \( \operatorname{det}\left(\mathrm{B}^{-1} \mathrm{AB}\right) \) is equal to📲PW App...
WebA determinant of 0 implies that the matrix is singular, and thus not invertible. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called Cramer's rule, and can only be used when the determinant is not equal to 0.
