Question
Let $\mathbf{u}=3 \mathbf{i}-2 \mathbf{j}, \mathbf{v}=2 \mathbf{i}+4 \mathbf{j},$ and $\mathbf{w}=2 \mathbf{i}$ and perform the indicated operations.$$2 u-3 v$$
Step 1
This gives us $2\mathbf{u} = 2(3\mathbf{i} - 2\mathbf{j}) = 6\mathbf{i} - 4\mathbf{j}$ and $3\mathbf{v} = 3(2\mathbf{i} + 4\mathbf{j}) = 6\mathbf{i} + 12\mathbf{j}$. Show more…
