assuming you have written this correctly:
(i) can be re-phrased: |u|,|w| < |y|,|v|
this is easy, note that if you have a vector of the form (a,0), its norm is |a|.
(ii) you can use a similar trick for this, as well. note that (a,0).(b,0) = ab.
I have no i dea where to go with this question. i just started guessing vectors.
Find vectors u, v, w, y Belong to R^{2}(i) |u|< |v|, |v|> |w|, |w|< |y|, |y| > |u|
(ii)|u|< |v| < |w| and y.u > y.v, y.v < y.w
I would appreciate any help thanks
