pls teach me position vectors

[velvet frigate]

I dont underdtand how the answer got the ob - oa stuff im so fking confused

[subtle cloud]

,rccw

[subtle cloud]

you mean how they got $\vec{OB}-\vec{OA}$?

[reef brook]

Kokichi

[velvet frigate]

Yes

[subtle cloud]

iirc that's a proof question

did your teacher taught you this?

[velvet frigate]

Idk i missed out the classes on vectors and it was months ago

[solid yew]

Do you know the parallelogram law

[velvet frigate]

I was sick

[velvet frigate]

Yeah vaguely

[solid yew]

this thing

[velvet frigate]

Its like tjis right

[velvet frigate]

Yea

[subtle cloud]

this explains it https://youtu.be/hNZ5jPSuYfU

[velvet frigate]

I dont understand where they got the o’s from

[solid yew]

So we can represent AB as AO + OB

[subtle cloud]

they draw a diagram and represent things

[solid yew]

where O is some point between A and B

[velvet frigate]

Wait what about the coordinates thing then

[velvet frigate]

Like i dont understand why they minused it

[subtle cloud]

minus means you're going on left

like they used same thing for vector ab

but different variables

[velvet frigate]

Deadass im gonna fail

Nvm its 12 am rn ill wake up tomorrow morning and watch a bunch of vids about it

Ty for help

[subtle cloud]

don't mention it
