Cool, thanks very much guys. Makes sense now!

Hey, this isn't for homework per se, but if anyone could lend me a hand figuring this out I'd appreciate it a lot! Homework Statement Determine whether Q is a subspace of R2/R3 in the following cases: Homework Equations Q = \{\left v = \left( v1, v2, 0 \right) | v1,v2 \in R...

Thanks a million guys, that's really helped me (finally) understand this stuff.

Brilliant! That makes perfect sense to me. Thanks very much for clearing that up. So if the last row does reduce to 0 0 0 after row reducing, then it's safe to say that the vectors are dependent?

Hi all, I have been studying Linear Algebra for an upcoming exam, and one question has puzzled me slightly! How do you determine of a vector in R4 is linearly independent? Given three vectors, each with 4 rows, I know you are meant to arrange them into a matrix, like this: \[ \left(...
