Problem:
Find the projection of the first vector onto the second:
$\left(
\begin{array}{c}
 0 \\
 3 \\
 -1 \\
 -1 \\
 0 \\
 0 \\
\end{array}
\right)$,
$\left(
\begin{array}{c}
 1 \\
 -3 \\
 -1 \\
 0 \\
 0 \\
 -1 \\
\end{array}
\right)$.
Answer:
$\left\{-\frac{2}{3},2,\frac{2}{3},0,0,\frac{2}{3}\right\}$
