Linear Algebra: 6. (5 points) If addition and scalar multiplication is redefined on R2 in the following way, show it is not a vector space. (21,91) + (x2, y2) = (2+ + 22,41 + y2) and c(, y) = (cx,y)
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...
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...
Consider R2 with the usual vector addition and the following strange scalar multiplica- tions. Show that these do not form a vector space over R by identifying the problematic axiom(s) and giving a counterexample for each (a) c* (x1,x2)= (0, cr2) (b) c (r1, )(cr,r2) (c) c0(x1,T2-ĺ (cr2, cr) otherwise
7. Let V = {(x,y)|x,YER}. Suppose addition and scalar multiplication are defined using the following non-standard rules. [5 marks] (x,y,)+(x2,y2) = (y2 + y2,X, + x) c(x,,y.) = (cx ,2cy) where c is any real number. a. Find the result of (1, -2) + (4, -3) under the above operations.
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....
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.
1. Why the following sets are not vector space? with the regular vector addition and scalar multiplication. a) V = {E: * > 0, y 20 with the regula b) V = {l*: *y 2 o} with the regular vector addition and scalar multiplication. c) V = {]: x2+y's 1} with the regular vector addition and scalar multiplication. 2. The set B = {1,1+t, t + t2 is a basis for P, the set of all polynomials with degree less...
For each of the following sets, indicate whether it is a vector space. If so, point out a basis of it; otherwise, point out which vector-space property is violated. 1.The set V of vectors [2x, x2] with x R2. Addition and scalar multiplication are defined in the same way as on vectors. 2.The set V of vectors [x, y, z] R3 satisfying x + y + z = 3 and x − y + 2z = 6. Addition and scalar...
please answer the question below Show that the set R2, equipped with operations (x1, y1)F(x2, y2) = (x1 + x2 + 1, y1 + y2 – 1) A: (2, 3) = (Ag+1 – 1, 2g - A+1) defines a vector space over R. Show that the vector space V defined in question 1 is isomorphic to R² equipped with its usual vector space operations. This means you need to define an invertible linear map T:V R2.
