Since so many people have replied, here is the list
I haven't gone through the entire book yet, but so far this is what I have found (if I misread or am completely wrong about my correction, I apologize)
1) Page 21- Opposite angle identity should be cos(-x) = cos(x)
Page 21- Add/sub formulas should be cos(a+b) = cos(a)cos(b) - sin(a)sin(b)
2) Page 23- #3: No solutions are correct, so see the answer in the back for the
"real" problem"; #4: Should say "...expresses f(n+2)..."; answer (D) and (E) are
the same.
3) Page 28- #16: Should be "x^3 - 3x^2 + 6x -4 = 0 "
4) Page 93- #17: Should be f'(1) = -1
5) Page 342- #38: Should be "if n = 1" (not n = -1)
