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. 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.

Web· A square matrix A is invertible if and only if det (A) ≠ 0. A matrix that is invertible is often called non-singular and a matrix that is not invertible is often called singular. · If A is a square matrix then: · If A is a square matrix with a row or column of all zeroes then: det (A) = 0 and so A will be singular.
