A primer of linear algebra Chapter one - UGA math department

(a) We can show that {w,x,y,z} is not a spanning set for R4 by finding a vector u in. R. 4 such that u /? span{w,x,y,z}. One such vector is u = (1,2,3,a) where ...

If we use the set notation, then we write the relation as R ? Z × Z, and we have (a, b) ? R if and only if a ? b is divisible by n. Proof. We need to prove that ...
