2x2 Matrix Adjoint & Adjugate Solver
Linear Algebra Guidelines: For a $2 \times 2$ matrix $\begin{pmatrix} a & b \\ c & d \end{pmatrix}$, the adjoint (adjugate) matrix is formed by swapping $a$ and $d$, and changing the signs of $b$ and $c$ to get $\begin{pmatrix} d & -b \\ -c & a \end{pmatrix}$. Enter matrix elements below.
