Let V be the set of all ordered triples of real numbers. For u =(u1, u2, u3) and v = (v1, v2, v3), we define the followingoperations of addition and scalar multiplication on V :
u + v = (u1 + v1, u2 + v2 ? 1, u3 + v3 ? 2) and ku = (ku1, ku2,ku3).
For example, if u = (1, 0, 3), v = (2, 1, 1), and k = 2 then
u + v = (1 + 2, 0 + 1 ? 1, 3 + 1 ? 2) = (3, 0, 2) and 2u = (2 ·1, 2 · 0, 2 · 3) = (2, 0, 6).
Complete the following:
(a) Calculate (1, 1, 1) + (2, 2, 2).
(b) Show that (0, 0, 0) 6= 0.
(c) What is 0?
(d) State a vector space axiom that fails to hold. Give anexample to justify your claim.
