#./aufgabe26_en.tex#Find for arbitrary $ t\in\mathbb{R}$ the determinant and the rank of the matrix

\begin{displaymath} A=\left( \begin{array}{rrrr} 8 & -2 & 0 & 4 \\ -2 & 6 & 7... ... \\ -2 & 1 & t & 8 \\ 4 & -1 & 0 & 3 \end{array}\right)\ . \end{displaymath}


Which $ t$ permit an invertible $ A$? Find $ A^{-1}$ for $ t=1$.
