Consider the vector space V = C2with scalar multiplication over the real numbers R, and let T : V → V be the linear operator defined by T (z1, z2) = (z1 − iz2, z2 − z2) . Let W be the cyclic subspace of V generated by w = (1 + 2i, 1 + i).
5.1 Find the T–cyclic basis β for W generated by w.
5.2 Find the characteristic polynomial of TW .
5.3 Find [TW ]β. 5.4 Explain whether T = TW
