Question

Given points A and B, find the components of the vector, v: A(-6,-5) and b(1,8) a. v=<7,13> b. v= <-5,3> c. v= <13,7> d. v=<8,-2> ** the v's have a arrow (->) on top**

are we adding  or subtracting?

usukidoll · Answer

can I have some more details?

usukidoll · Answer

u1+v1, u2+v2,...un+vn adding
v: A(-6,-5) and b(1,8)
-6+1,-5+8
-5,3

u1-v1, u2-v2,...un-vn subtracting
-6-1.-5-8
-7,-13 
???????

hmm or the component could be the cos formula argh gotta look it up

usukidoll · Answer

maybe vector projection

anonymous · Answer

thats all that they said

usukidoll · Answer

hmmm did they give you an angle?

anonymous · Answer

no they didnt

usukidoll · Answer

hmmm then the projection vector formula won't work well.

usukidoll · Answer

only way I could think of that fits your multiple choice is the addition

anonymous · Answer

yeah, i found other typos on my assignment so i am going to talk to my teacher about that. also thanks helping me :D
