(Change of basis) Let be an orthonormal basis of Vn, so that (1.114) and (1.115) hold for an arbitrary vector v. In particular, we can write
a) Show that, with A = (aij),
Thus the matrix A provides the link between the components of v with respect to the
two orthonormal bases. [Hint: Write and dot both sides with ei* for I = 1, …, n.]
b) Show that the j th column of A gives the components of ej with respect to the basis and the ith row of A gives the components of ei* with respect to the basis
c) Show that A is an orthogonal matrix (Section 1.13).
