Question
Transcribed Image Text:Problem 8 (Diagonalization). Let T : P2 → P2 be defined as,
T(p(x)) = xp'(x).
1. Find the eigenvalues and eigenvectors of T.
2. Show that T is diagonalizable and write P2 as the sum of the eigenspaces of T.
Problem 9 (Basis). Determine all the values of the scalar k for which the following four matrices form a basis

Problem 10 (Orthogonality). In this question, we will again see how orthogonality makes computations sim-
pler.
1. Let u1,..., un be an (ONB) of a finite-dimensional inner product space V. Let v = c1u1 + ... + Сnun and
w = d1μ1 + ... + dnUn be any two elements of V. Prove that (v, w) = c1d1 + ... + Cndn.
2. Write down the corresponding inner product formula for an orthogonal basis.
