1. The problem statement, all variables and given/known data This is more of a general question that doesn't require any math. (at least I don't think so) 2. Relevant equations Requires knowledge of linear algebra. 3. The attempt at a solution Well, right now i'm learning about vector spaces. But when I was learning about vector rows and vector column's, I had this question that my book didn't talk about. If the vector row's and vector column's are components of a vector, where do the numbers come from? And I know about how you represent a vector on a xy plan. But where do the numbers come from the vector it's self?
