Let B be the ordered basis for \(\mathbb{R}^3\) given by \(B=\left\{\begin{bmatrix} 1\\ -1\\ 0\end{bmatrix}, \begin{bmatrix} 0\\ 2\\ 1\end{bmatrix}, \begin{bmatrix} -1\\ 0\\ -2\end{bmatrix}\right\}\). Using this ordered basis, apply the Gram-Schmidt orthonormalization process to find a corresponding orthonormal basis for W.
