I get confused what to do first.
The operations. I know how to find determinant, how to do gauss and so on. but I tend to mix them up in questions. which to use
but I have a question that asked me:
consider the following vectors R3: u-(1,2,3) v-(-1,1,2).
describe those 2 vectors for which they are a basis.
give an example of another vectors besides u and v that belongs to the set for which u and v are a basis.
I don't think I clearly get this question
Hey there I was just wondering? Can 2 vectors span R3?
let's say I have i and j vectors. What are the examples that show i and j are the basis of R3 and span R3?
