Vector Space - Yes or No? Example 2

[@zerodegreescelsius]

This is the counter-example I've been looking for! Thanks so much!

[@correntkatcorrentinfo6644]

If I'm unable to come up with a counter-example, how would I show using the vector space axioms that the set is not a vector space over R^2

[@chemaflores2569]

did someone found example 3? pleasee tell me

[@imboredsauce]

Thank you, thank you, thank you, thank you, thank you. I really needed this. I feel that Linear Alg goes over my head especially the proofs

[@l3aIIin23]

+imboredsauce im in the same boat

[@KingofHearts67]

Ohhh seriously pictures are so helpful, my professor just throws textbooks worth of math talk and numbers at me and it all goes on one ear and out the other.

[@looc1612]

where is the third????

[@sln7736]

Third example was good

[@albega127]

why are using (5,0) and (0,2)? in my opinion absolutely that example is wrong because you take the vector in 4th quadrant and we should proof the vector either in 1st quadrant or 3rd quadrant. please correct me if I'm wrong

[@amarashah3430]

hez taking (5,0) and (0,-2) so taking 4th quad.

I want this guy to get hired on my University

[@Knights2theEnd]

he uses simple examples, which isn't the best if every example is easy. The harder example, #3, is non-existent.

Hi PatrickJMT can you explan what and just how BIG is the Graham number is what it means, how Graham figured out this number?

[@pandabear4321gogo]

Go on Numberphile, you might get distracted with the many videos, but there is an interview (and other videos) with the man himself, Graham.
