Problem:
Find the projection of the first vector onto the second:
$\left(
\begin{array}{c}
 -2 \\
 \frac{4}{5} \\
 \frac{14}{5} \\
 \frac{14}{5} \\
 -3 \\
\end{array}
\right)$,
$\left(
\begin{array}{c}
 -\frac{2}{5} \\
 -\frac{13}{5} \\
 \frac{13}{5} \\
 \frac{7}{5} \\
 -\frac{1}{5} \\
\end{array}
\right)$.
Answer:
$\left\{-\frac{263}{980},-\frac{3419}{1960},\frac{3419}{1960},\frac{263}{280},-\frac{263}{1960}\right\}$
