The vectors \vec{v}_1 = \begin{bmatrix} \frac{1}{\sqrt{2}}\\ \frac{1}{\sqrt{2}}\end{bmatrix}, \vec{v}_2 = \begin{bmatrix} \frac{1}{\sqrt{2}}\\ -\frac{1}{\sqrt{2}}\end{bmatrix} form an orthonormal basis of \mathbb{R}^2 with respect to the euclidean inner product. Let \vec{u} = \frac{5}{\sqrt{2}}\vec{v}_1 - \frac{1}{\sqrt{2}}\vec{v}_2. Use Parseval's Formula (Property 3) to evaluate \| \vec{u}\|^2. Hint: Note that x_1 and x_2 are the coefficients of the linear combination. In this case, x_1 = \frac{5}{\sqrt{2} and x_2 = -\frac{1}{\sqrt{2}}
