?In Exercise 6, we should also let ( , , ) x y z w.. = w w w .
?In Exercise 7, it should be b2 =v.. 2 , not b2 =v.. . Also, the law of cosines is:
c2=a2+b2.2abcos? .

?Page 44, the second line from the top of the page should be:
z’=rcos(?+?)=rcos?cos?.rsin?sin?=zcos?+ysin?.
?Page 56. The text reads, “Then, we compute the signed distance as before, that is,
( ) 0 . n…p.. =d ,” but it should be noted that it is only the signed distance if the
normal vector has been normalized; otherwise the distance will be scaled.
?Page 59, Exercise 4. It says T T 1
y y y y R R = R R = . The ‘1′ should be an I for
identity matrix; that is, it should be: T T
y y y y RR =RR =I.
