**Page 33** Where it says theta(C) it should be theta(B), and where it says theta(B) it should be 90 degrees.

**Page 47** In section 3.7.1.3 O_ij should read O_ij = sigma(k=1,r) M_ik N_kj

**Page 51** The reference to 3.6 should be 3.7 (and the reference to 3.7 should be 3.6). Also the
reference to the dot product should be 3.8.1.2 and 3.8.1.2 should reference 3.6.
