Matrix inversion is a fundamental operation in mathematics, engineering, computer science, and physics. A 2×2 matrix can be inverted quickly if it has a non-zero determinant. The formula for the inverse of a 2×2 matrix: A=[abcd],A−1=1ad−bc[d−b−ca]A = \begin{bmatrix} a & b \\ c & d \end{bmatrix}, \quad A^{-1} = \frac{1}{ad – bc} \begin{bmatrix} d &…
