A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

#./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$.
