Question

vectors!!! help me refresh

Answer 1

so think if we are at the point (0,0) and we use vector d=(1,2) to get to our new position

well what will e=-d=(-1,-2) do?

Answer 2

it will be the reverse process, right

Answer 3

yeah

Answer 4

so what i can't recall is how to solve this problem...i guess e = -d = -24 meters is answer but not sure

Answer 5

well if we are considering R^2 ( 2 dimensions ) then tipically we would call in the x direction "east" so our vector d will be d = (24,0) and -d=(-24,0)

Answer 6

these are vectors not real numbers.

Answer 7

oh ya...i gotcha...its the graph...ok now help me totally understand it...lets say now
so the answer would be e = 3d = (72,0) ???
