The column vector notation of four vectors is shown below.
$$
P=\left(\begin{array}{l}
-8 \\
-8
\end{array}\right) \quad Q=\left(\begin{array}{l}
3 \\
6
\end{array}\right) \quad R=\left(\begin{array}{l}
1 \\
5
\end{array}\right) \quad S=\left(\begin{array}{c}
-5 \\
7
\end{array}\right)
$$
Find
(i) \(\overrightarrow{P Q}\)
(ii) \(\overrightarrow{R S}\)
(iii) \(-\overrightarrow{P Q}-\overrightarrow{R S}\)
i) \(\left(\begin{array}{l}11 \\ 14\end{array}\right)\)
ii) \(\left(\begin{array}{l}-6 \\ 2\end{array}\right)\)
iii) \(\left(\begin{array}{l}-5 \\ -16\end{array}\right)\)
