7. Let V = {(x,y)|x,YER}. Suppose addition and scalar multiplication are defined using the following non-standard...
If addition and scalar multiplication is redefined on R2 in the following way, show it is not a vector space. (x1, yı) + (x2, y2) = (x1 + x2, Y1 + y2) and c(x, y) = (cx, y)
linear algebra 1. Determine whether the given set, along with the specified operations of addition and scalar multiplication, is a vector space (over R). If it is not, list all of the axioms that fail to hold. a The set of all vectors in R2 of the form , with the usual vector addition and scalar multiplication b) R2 with the usual scalar multiplication but addition defined by 31+21 y1 y2 c) The set of all positive real numbers, with...
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.
Hello I need help understanding these questions show the steps. Thanks. Rather than use the standard definitions of addition and scalar multiplication in R3, suppose these two operations are defined as follows. With these new definitions, is R3 a vector space? Justify your answers. (a) (x1, Y1, 21) + (x2, Y2, 22) = (x1 + x2, Y1 + y2, 21 + 22) c(x, y, z) = (cx, 0, cz) O The set is a vector space. O The set is...
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)
b) Show that V -(x, y, 2)lr-y2z 2 is not a vector space under the standard operations of vector addition and scalar multiplication.
Let y be a differentiable function such that y' – 7y = 7, where y' is the first derivative of y. Define addition yı y2 = yı + y2 + 1 and scalar multiplication c Oyı = cyı + c – 1. Let V be the set of all differentiable functions that solve y' – 7y = 7. Note that these functions fit the form y = ket – 1. Determine if V is a vector space.
Let clo, π] := {f : [0, π] → R I f is continuous). With addition and scalar multiplication defined in the usual way, this is a vector space. Let the inner product on CO,T] be defined analogous to (21), that is, (me) :-o u(z)r(z) dz. sinx and g(x) = 2.2. Which is "bigger": f or g? (a) Let f(x) (b) g? xplain. (c) Find a nontrivial function in CIO, π], which is orthogonal to f. d) Find a nontrivial...
Let V = R2 with the following operations: (zı, yı) + (2 2,32) = (x1 +T2-1, yı +B2) (addition) c(x1, y) = (czi-e+ 1, cy) where c E R (scalar multiplication). Then V is a vector space with these operations (you can take this as given). (a) (2) Let (-2,4) and (2,3) belong to V and let c -2 R. Find ca + y using the operations defined on V. (b) (2) What is the zero vector in V? Justify....
Let V be the set of vectors [2x − 3y, x + 2y, −y, 4x] with x, y R2. Addition and scalar multiplication are defined in the same way as on vectors. Prove that V is a vector space. Also, point out a basis of it.
