- ProofProve in full detail that M2,2, with the standard operations, is a vector space.arrow_forwardFind an orthonormal basis for the subspace of Euclidean 3 space below. W={(x1,x2,x3):x1+x2+x3=0}arrow_forwardProof Prove that if S1 and S2 are orthogonal subspaces of Rn, then their intersection consists of only the zero vector.arrow_forward
- 13. Finish verifying that is a vector space (see Example 6.4).arrow_forwardSubsets That Are Not Subspaces In Exercises 7-20 W is not a subspace of vector space. Verify this by giving a specific example that violates the test for a vector subspace Theorem 4.5. W is the set of all vectors in R3 whose components are nonnegative.arrow_forwardTrue or False? In Exercises 49 and 50, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. a To show that a set is not a vector space, it is sufficient to show that just one axiom is not satisfied. b The set of all first-degree polynomials with the standard operations is a vector space. c The set of all pairs of real numbers of the form (0,y), with the standard operations on R2, is a vector space.arrow_forward
- Determine subspaces of Mn,n In Exercises 2936, determine whether the subsetMn,n is a subspace ofMn,nwith the standard operations. Justify your answer. The set of all nn diagonal matricesarrow_forwardSubsets That Are Not Subspaces In Exercises 7-20 W is not a subspace of vector space. Verify this by giving a specific example that violates the test for a vector subspace Theorem 4.5. W is the set of all vectors in R2 whose second component is the square of the first.arrow_forwardDetermining Subspace of R3 In Exercises 37-42, determine whether the set W is a subspace of R3 with the standard operations. Justify your answer. W={(a,a3b,b):aandbarerealnumbers}arrow_forward
- Subsets That are Not Subspaces In Exercises 7-20, W is not a subspace of V. Verify this by giving a specific example that violates the test for a vector subspace Theorem 4.5. W is the set of all vectors in R2 whose components are integers.arrow_forwardV Let be the set of all functions of the form f(x) = ae* +b\x , a,D ER This set is a subset of the set of all continuous functions on (0,"). it is also a subspace. (a) Verify the closure axioms explicitly for functions in this form. (b) The set S is an obvious spanning set, since the given function form is linear combinations of that set. You need to show independence. While use of the Wronskian is a result from Differential Equations, it is NOT a result that is part of the body of theorems for this class, and so you can't bring it in here. Verify the independence of *S by directly setting up the equation that defines independence. That should give you an equation with C1, C2 and the function of X. The way to test this is to just pick two arbitrary values of X and use them to generate an easy system of two linear equations that can be solved for C and C2.arrow_forwardNumber 8 4.1 linear algebraarrow_forward
