Let $V=\operatornamespan}\left\{\left(\begin{array}{1}1 11 1\end{array} ight),\left(\begin{array}{c}-1 W11\end{array} ight) ight\}$ and $u=\left(\begin{array}{1}l 21\end{array} ight)$. a. Find $\operatorname{proj}_{v} u$. b. Find the angle between $V$ and $u$ (you can give your result in terms of an inverse cosine). c. Find the distance from $u$ to $V$. d. Find $V^{\perp}$. CS.JG.090
