Problem:
Normalize the following vector:
$\left(
\begin{array}{c}
 -\frac{19}{9} \\
 -\frac{1}{9} \\
 -\frac{26}{9} \\
 \frac{7}{9} \\
\end{array}
\right)$.
Answer:
$\left(
\begin{array}{c}
 -\frac{19}{\sqrt{1087}} \\
 -\frac{1}{\sqrt{1087}} \\
 -\frac{26}{\sqrt{1087}} \\
 \frac{7}{\sqrt{1087}} \\
\end{array}
\right)$
