(a) Given a finite-dimensional inner product space V and a linear operator T : V → V, explain how we determine whether there exists an ordered orthonormal basis B for V such that [T]B is diagonal, without finding such a basis. Then, explain how we may actually compute such a basis. (b) Illustrate this procedure in the case V = M2x2(C) with standard inner product, and T: V → V given by the transformation T(A) = CA, where C = i
