Question
In Exercises $5-10$ , use the vectors $u=\langle 2,2\rangle, v=\langle- 3,4\rangle$ and $ w=\langle 1,-4\rangle$ to find the indicated quantity. State whether the result is a vector or a scalar.$$\mathbf{u} \cdot \mathbf{u}$$
Step 1
In this case, we have the vector $\mathbf{u} = \langle 2,2 \rangle$ and we want to find $\mathbf{u} \cdot \mathbf{u}$. Show more…
