4 Let R2 be the set of all ordered pairs of real numbers equipped with the operations: addition defined by (21,02) (91, 92) = (21 41, 22 y2) and scalar multiplication defined by c(x1,22) = (cx1,Cx2), herece R is a scalar. Note that the operation addition here is non standard. Is R’ in this case a vector space ? (Justify your answer)
VECTOR SPACES LINEAR ALGEBRA Let V be the set of all ordered pairs of real numbers, and consider the following addition and scalar multiplication operations on u = (u1, u2) and v = (v1, v2): u + v = (u1 + v1 + 1, u2 + v2 + 1), ku = (ku1, ku2) a) Show that (0,0) does not = 0 b) Show that (-1, -1) = 0 c) Show that axiom 5 holds by producing an ordered pair -u...
V01 (version 953): Let V be the set of all pairs (x,y) of real numbers together with the following operations: (x1, yı) © (C2, y2) = (x1 + 22,41 + y2) cº (x, y) = (Acc, 4cg). (a) Show that scalar multiplication distributes over scalar addition, that is: (c+d) 9 (z, 3) = c+ (x, y) #de (x, y). (b) Explain why V nonetheless is not a vector space.
[2 marks] Let V be the set of all ordered pairs of real numbers (u1, uv) with uj > 0. Consider the following addition and scalar multiplication operations on u = (u1, u2) and v = (v1, v2): u + v = (421, uz + v2), ku = (kuq, kuz) If the set V with the above operations satisfies Axiom 5 of a vector space (i.e., the existence of a negative element), what would be the negative of the vector...
