WitrynaQuestion: If A = a b c d , then A is invertible if ad − bc ≠ 0, in which case A−1 = 1 ad − bc If A = , then A is invertible if ad − bc ≠ 0, in which case A −1 = . If ad − bc = 0, … WitrynaIf det ( A )= 0, then A is not invertible. Proof There is an analogous formula for the inverse of an n × n matrix, but it is not as simple, and it is computationally intensive. The interested reader can find it in this subsection in Section 4.2. Example The following theorem gives a procedure for computing A − 1 in general. Theorem
