Question

Find the unit vector that has the same direction as the vector v = –12j

Answer 1

given a vector v, the unit vector u that points in the same direction v is

\[\Large \vec{u} = \frac{1}{|\vec{v}|}*\vec{v}\]

Answer 2

the portion |v| is the length of vector v

Answer 3

i did some research and figured it was a -v

Answer 4

what do you mean?

Answer 5

-12v/12v=-v

Answer 6

I think you meant to say -j

Answer 7

or negative j sorry so many letters, -12j/12j=-j

Answer 8

-12j = 0i + (-12j) = <0, -12>

Answer 9

this vector is of length 12

Answer 10

so you multiply the components of <0, -12> by 1/12

Answer 11

to get <0,-1> which is really -j

Answer 12

same answer i found just written differently

Answer 13

yeah
