Question
Find $2 \mathbf{u},-3 \mathbf{v}, \mathbf{u}+\mathbf{v},$ and $3 \mathbf{u}-4 \mathbf{v}$ for the given vectors $\mathbf{u}$ and $\mathbf{v} .$$$\mathbf{u}=\langle 0,-1\rangle, \quad \mathbf{v}=\langle- 2,0\rangle$$
Step 1
To do this, we multiply each component of $\mathbf{u}$ by 2. So, $2\mathbf{u} = 2\langle 0,-1\rangle = \langle 2*0, 2*(-1)\rangle = \langle 0,-2\rangle$. Show more…
