### Solution to Application Example 7.11

Calculation of the inverse of $J¯0$, that is. $J¯0−1$.

${\left({\overline{J}}^{0}\right)}^{-1}=\frac{\mathrm{A}\mathrm{d}\mathrm{j}\left({\overline{J}}^{0}\right)}{det\left({\overline{J}}^{0}\right)}\text{,}$

where Adj $J¯0$ is the adjoint of matrix $J¯0$ and det$J¯0$ = |$J¯0$| is the determinant of $J¯0$.

The adjoint of $J¯0$ is obtained by first taking the ...
