EDIT: I think i screwed up and posted in the wrong section. Sorry. Should i make a new one to the correct place? Can this one be moved?
Hello. I have a couple of problems here, that i will have to translate from another language, so I am not 100% sure if I am using the correct terms.
(1) Let u, v, w ∈ ℝn be vectors. Find out if the vector u+v is an element of the group (subset?) (2u-v, 2u-w, 2w-u).
(2) Show that the ℝn vectors u=(a,1,-1), v=(b,-1,2) and w=(c,1,3) are linearly dependant exactly when c-4b-5a=0.
So, i don't know what to do with these.
