W={(s,t,s+t):sandtarerealnumbers}arrow_forwardProof Prove that if S1 and S2 are orthogonal subspaces of Rn, then their intersection consists of only the zero vector.arrow_forwardDetermine 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_forward
- Subsets 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_forwardCalculus Let B={1,x,ex,xex} be a basis for a subspace W of the space of continuous functions, and let Dx be the differential operator on W. Find the matrix for Dx relative to the basis B.arrow_forwardCalculus Use the matrix from Exercise 45 to evaluate Dx[4x3xex]. 45. Calculus Let B={1,x,ex,xex} be a basis for a subspace W of the space of continuous functions, and let Dx be the differential operator on W. Find the matrix for Dx relative to the basis B.arrow_forward
