Chapter 6: Problem 4
Find the cosine of the angle between \(x\) and \(y\) where \(x=\left[\begin{array}{l}1 \\ 0 \\ 0\end{array}\right] y=\left[\begin{array}{l}2 \\ 2 \\ 2\end{array}\right]\) \(\begin{array}{l}\text { 2. } x=\left[\begin{array}{c}1 \\ -1 \\ 1 \\\ -1\end{array}\right] & y=\left[\begin{array}{c}-1 \\ 0 \\ 1 \\\ 0\end{array}\right] \\ \text { 3. } x=\left[\begin{array}{c}2 \\ 1 \\\ -2\end{array}\right] & y=\left[\begin{array}{c}4 \\ 2 \\\ -4\end{array}\right]\end{array}\)
