Im in first year of high school btw not a genius

#

they behave very much the same as 2d vectors

#

what part is a struggle?

neon kettle Jan 12, 2025, 7:48 PM

#

the only point of confusion might be the sqrt root thing, thats just pythagoras in 3d

#

can you translate this to english ? idk what this language is

#

icy cobalt can you translate this to english ? idk what this language is

they tell basics of 3d vectors basicly idk maybe chat gpt

#

can tell

icy cobalt Jan 12, 2025, 9:23 PM

#

firstly, you need to understand one of the most important ideas in math
which is scaling

#

to be in the picture

#

i will explain it to you

#

this is youre image, with side's length of 1, seems to be very small to me, so i want to make it bigger !
is that alright ?

#

if you understand the concept of scaling @river gazelle, then we can skip this part

river gazelle Jan 12, 2025, 9:30 PM

#

yeah ik what u mean

#

#

y mean this right?

icy cobalt Jan 12, 2025, 9:30 PM

#

yes

#

we will apply this concept but with vectors this time

#

neon kettle the only point of confusion might be the sqrt root thing, thats just pythagoras ...

yeah ik its 3d straight line basicly right

#

mainly I don't understand how they move

#

cuz 2d is simple enough its the easiest path from A to B

#

my head does not function how it works in 3d logically

icy cobalt Jan 12, 2025, 9:32 PM

#

ok, this need some work @river gazelle

river gazelle Jan 12, 2025, 9:33 PM

#

i keep seeing shit like this and it makes no sense

#

if i could spin this photo i would understand it but yeah

river gazelle Jan 12, 2025, 9:34 PM

#

river gazelle i keep seeing shit like this and it makes no sense

cuz i cant tell if the a.z is straight line up or is it sliding slightly toward a

https://www.geogebra.org/calculator
here is this website
you can visualize all the 3d vectors that you might think of
the more you spend time on it, the more understanding

Calculator Suite - GeoGebra

#

just play around with it

river gazelle Jan 12, 2025, 9:36 PM

#

yea ik but i think your brain works better are you able to tell if az is straight line or not?

#

like straight in z axis

icy cobalt Jan 12, 2025, 9:36 PM

#

yes, so?

river gazelle Jan 12, 2025, 9:37 PM

#

okay thanks cuz I have coordination issue with my brain and thats why I cant comprehend this as well

#

the photos are issue not the solving

#

thanks a lot

np

river gazelle Jan 12, 2025, 9:37 PM

#

how do u close this one

icy cobalt Jan 12, 2025, 9:37 PM

#

.close

river gazelle Jan 12, 2025, 9:38 PM

#

It started to be night time and my brain started functioning sorry for wasting time

#

.close
