Not sure that there is one - are you referring to the 4th edition?

Assuming you are using version 4: the error isn't on page 95, but in the solution set. The answer itself is correct. The errors made are just typographical.

On page 339 #3. The first limit where it says lim x-> n- [x] = -(n+1) should instead read as lim x->-n- [x] = -(n+1). (notice the negative sign in the limit) Similarly the limit should be the same for the first absolute value. They are just missing the negatives.
