Question

Find the component form and length of the vector u if the initial point is (-1,4) and the terminal point is (2,2).

Answer 1

this is just a distance between 2 points type question right?

Answer 2

if we move the points by (1,-4) we can solve this simpler

Answer 3

(-1,4) (2, 2)
(1,-4) (1,-4)
------------
(0,0) (3,-2)

now we have a vector at the origin

Answer 4

component parts are: 3i -2j

Answer 5

length is sqrt(9+4)

Answer 6
