Problem:
Find the projection of the first vector onto the second:
$\left(
\begin{array}{c}
 \frac{3}{2} \\
 -\frac{3}{2} \\
 1 \\
 -\frac{1}{2} \\
 -\frac{1}{2} \\
\end{array}
\right)$,
$\left(
\begin{array}{c}
 \frac{3}{2} \\
 \frac{3}{2} \\
 -\frac{5}{2} \\
 -\frac{5}{2} \\
 -\frac{1}{2} \\
\end{array}
\right)$.
Answer:
$\left\{-\frac{2}{23},-\frac{2}{23},\frac{10}{69},\frac{10}{69},\frac{2}{69}\right\}$
