Question
Find the dot product $\mathbf{v} \cdot \mathbf{w}$ and the angle between $\mathbf{v}$ and $\mathbf{w}$.$$\mathbf{v}=3 \mathbf{i}-4 \mathbf{j}+\mathbf{k}, \quad \mathbf{w}=6 \mathbf{i}-8 \mathbf{j}+2 \mathbf{k}$$
Step 1
Step 1: First, we write down the given vectors $\mathbf{v}$ and $\mathbf{w}$: $$ \mathbf{v}=3 \mathbf{i}-4 \mathbf{j}+\mathbf{k}, \quad \mathbf{w}=6 \mathbf{i}-8 \mathbf{j}+2 \mathbf{k} $$ Show more…
