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 following operations 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 an example to justify your claim.

Let S be the set of all ordered pairs of real numbers. Define scalar multiplication and addition on S by: α(x1,x2)=(αx1,αx2) (x1,x2)⊕(y1,y2)=(x1 +y1,0) We use the symbol⊕to denote the addition operation for this system in order to avoid confusion with the usual addition x+y of row vectors. Show that S, together with the ordinary scalar multiplication and the addition operation⊕, is not a vector space. Test ALL of the eight axioms and report which axioms fail to hold.
