\section{Inverse}
For a 3x3 non-singular matrix $A$
with a determinant $|A|$ defined
by \begin{equation}
A=\begin{bmatrix}
a_{11} & a_{12} & a_{13} \\ a_{21} & a_{22} & a_{23} \\ a_{31} & a_{32} & a_{33}
\end{bmatrix}
\end{equation}
we can calculate the inverse
defined by as \begin{equation}
A^{-1}=\frac{1}{|A|}
\begin{bmatrix}
