Our expert help has broken down your problem into an easy to learn solution you can count on. question: 1. let a = 1 −1 2 0 1 −3 . find a vector x in n (a) and verify that it is orthogonal to the rows of a. 2. let a 1 = 1 0 1 , a2 = 1 2 −1 . find a unit vector ˆx that is orthogonal to both a 1 and a 2 . 3. We apply t to the standard basis 1, x, x2, x3 to get 1 1 , 0 1 , 0 1 , 0 1 . 3. let v be a vector space, and suppose that s1 ⊆ s2 ⊆ v , where s1 and s2 are subsets (not necessarily subspaces). prove that if s2 is linearly independent, then so is s1. =⇒ v2 = (a −3i)v1 = −2 −2 . 4. let a be a 3 × 3 matrix that has v1,v2,v3 as a jordan chain of length 3 and let b be the matrix whose columns are v3,v2,v1 (in the order listed). compute b−1ab. suppose the vectors v1,v2,v3 form a jordan chain with eigenvalue λ, in which case (a− λi)v1 = v2, (a− λi)v2 = v3, (a−λi)v3 = 0. Use change of basis matrices to compute the matrix for t relative to the basis b = 1 1 √ 2 , 1 1 − √ 2 . [suggestion: you can speed up your computations by setting α = 1 √ 2, β = 1 − √ 2, and then noting that (x − α)(x − β) = x 2 − 2x − 1.
