the typos in princeton's "cracking the gre math" b
as i'm sure many of you know, princeton's book is littered with typos, some more serious than others. i was wondering if anyone has found or compiled a list of these typos online? if so, it would serve as a useful reference and catchall. if you know of anything out there, please point the way.
Princeton Review Book
I would like the list. Could you please email it to josh at caltech dot edu? Thanks a bunch.

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)
