Question
In Problems 9-18, (a) find the dot product $\mathbf{v} \cdot \mathbf{w} ;(b)$ find the angle between $\mathbf{v}$ and $\mathbf{v}=2 \mathbf{i}+2 \mathbf{j}, \quad \mathbf{w}=\mathbf{i}+2 \mathbf{j}$
Step 1
The dot product of two vectors $\mathbf{v} = a\mathbf{i} + b\mathbf{j}$ and $\mathbf{w} = c\mathbf{i} + d\mathbf{j}$ is given by $ac + bd$. For the vectors $\mathbf{v} = 2\mathbf{i} + 2\mathbf{j}$ and $\mathbf{w} = \mathbf{i} + 2\mathbf{j}$, we have: \[ \mathbf{v} Show more…
