that's what a vector it. a stick with an arrow attached to it. unless it is an abstraction such as a tuple.

kek

>a vector is an arrow
lul engineers
>a vector is an n-tuple
lul computer "scientists"

Hey guys, can you check another one please.

ah x2 is negative and i subtracted it from the doubled length of x1, but i should have added it since it is negative??

an element of a vector space

>>8947893
how is it different than an n-tuple?

>>8947903
You can have a vector space that has an uncountable dimension such as the the vector spaces of continuous functions on the unit interval so there ia no way you can represent it as some soet of tuple.

>vector is an element of a vector space
>vector space is set of vectors
mathematical rigor at it's finest

>>8947944
Yea, we then define vectors as elements that form an abelian group witg an additional operation called scalar multiplication that distributes over the addition.

>>8947944
Don't try to reason with mathematicians

Just take their shit and run

>>8947920
>uncountable dimension
that's what n means in an n-tuple

>>8947972
No, you retard. Uncountable is means not countable as in there is no bijection.

>>8947979
Between the set and a subset of the natural numbers*

>>8947879
bump

>>8947961
Math is pretty much the only source of reason in this world. But i agree, take their shit and run.
