Linear Algebra

Can someone take a look please. Is this the correct solution?

Looks good

>drawing arrows for vectors

Thank you

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"

>a vector is a vector

fucking mathfags I swear

so what is a vector, victor?

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

how is it different than an n-tuple?

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

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

Don't try to reason with mathematicians

Just take their shit and run

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

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

Between the set and a subset of the natural numbers*

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

Fuck right off to /sqt/ cunt
