do you see the tips of the arrows? if so, where are the tips located?

OpenStudy (anonymous):

5 , 5

jimthompson5910 (jim_thompson5910):

let's pick on the upper arrow or vector first

OpenStudy (anonymous):

but jimwe have to show some working isnt it

jimthompson5910 (jim_thompson5910):

the arrow starts at (0,0) and the tip is at (3,5)

jimthompson5910 (jim_thompson5910):

do you see how I'm getting (3,5)?

OpenStudy (anonymous):

yep on x axis

jimthompson5910 (jim_thompson5910):

for the other tip, where is that located?

jimthompson5910 (jim_thompson5910):

which point?

OpenStudy (anonymous):

5 , 1

jimthompson5910 (jim_thompson5910):

good

jimthompson5910 (jim_thompson5910):

so you just add the corresponding components

jimthompson5910 (jim_thompson5910):

ie you add the x coordinates separately 3+5 = 8 and you add the y coordinates separately 5+1 = 6 So the resultant vector will have its tip at (8,6)

jimthompson5910 (jim_thompson5910):

Another way to visualize it is that you write it like this |dw:1365281146688:dw|
