Question 1141473
Let u = (2,1,2), v = (3,2,1) and w = (1,2,-5) be vectors in 3-dimension space.
(a). Represent u, v and w graphically of vectors in 3-dimension space.
Using what?
------------------- 
(b). Calculate u+v and show u,  v and u+v graphically in 3-dimension space.
u + v = (5,3,3)
Using what for graphs?
-----------
(c). Evaluate u+v+5w and 3u-v-2w
You do that.
