@Willie: Thank you, that explained it! I suggest you consider writing that textbook! gary: I have not seen or learnt about fields or finite fields yet. I'll keep an eye out for that though!

comment Help with the proof of the characterization of linearly dependent sets
@D B Lim: Thank you D B Lim! You're right, Lay has given me the impression that linear algebra is mostly about matrices... I'll pick the book up at my library right away! Thank you for the helpful suggestion!

comment Help with the proof of the characterization of linearly dependent sets
Thanks D B Lim! +1! Vector spaces are the next chapter in the book, so I'll have a go at these once I've had a look in that chapter.

comment Help with the proof of the characterization of linearly dependent sets
Thank you! I think I got it! Now the point with the second part, where v_1 is not zero, is that then not all numbers c_2 -> c_p can be zero (for it to be linearly dependent), which in turn leads to the fact that v_j is a linear combination of the preceding vectors... Have I kind of got it? I have at least got what I initially asked for, so I'm marking your post as the answer:)

comment Help with the proof of the characterization of linearly dependent sets
Sorry, I didn't mean to rephrase it. Do you mean that we're simply saying that v_1 is a trivial linear combination in this case; and that it could just as fine be a non-trivial combination as well (but for the sake of the proof we're assuming the former)?

comment For any prime $p > 3$, why is $p^2-1$ always divisible by 24?
@Theo: Sorry, I did not consider that! I will read that discussion. Thank you for letting me know! It was definitely not my intention to flood the front page. (I was going through the list of "low-quality posts" in the review section).
