Question
Given vectors u and v, find: (a) 2u (b) 2u+3v (c) $\mathbf{v - 3 u .}$$$\mathbf{u}=\langle- 1,2\rangle, \mathbf{v}=\langle 3,0\rangle$$
Step 1
We are asked to find 2u, which means we need to multiply vector u by 2. This is done by multiplying each component of the vector by 2. So, we have $2\mathbf{u} = 2\langle- 1,2\rangle = \langle- 2,4\rangle$. Show more…
