State the definition of parallel vectors.
Use vectors to show that the points form the vertices of a parallelogram. (1,1,3),(9,-1,-2),(11,2,-9),(3,4,-4)
Find \((\mathbf{a}) \mathbf{u} \cdot \mathbf{v},(\mathbf{b}) \mathbf{u} \cdot \mathbf{u},(\mathbf{c})\|\mathbf{u}\|^{2},(\mathbf{d})(\mathbf{u} \cdot \mathbf{v}) \mathbf{v}\) and \((e) u \cdot(2 v)\). $$ \mathbf{u}=\mathbf{i}, \quad \mathbf{v}=\mathbf{i} $$
Find the angle \(\theta\) between the vectors. $$ \begin{array}{l} \mathbf{u}=3 \mathbf{i}+4 \mathbf{j} \\ \mathbf{v}=-2 \mathbf{j}+3 \mathbf{k} \end{array} $$
