Typesetting errors in the text and in the solution manual (below).

Fix all of the 5th edition text with these corrections now.

Text:
Section 2.1, page 91, last line of "Example 2, Again" should say "f ^-1(x) = 2(x - 3)" [with parentheses].
Section 2.3, page 95, Theorem 2-3-8:  The second line says "If n is even, x = c ..." and should say "If n is even, xⁿ = c ...."
Section 3.2, page 128, Example 4, last offset line:  Has a tall right square bracket which should be omitted.
Section 3.2, page 138, B2. "a < 0" instead of "a > 0"
Section 3.6, page 176, line 4:  "Set that equal to 447 and solve" should have "477", not "447".
Section 4.1, page 203, B40.  (1 - x²)/2 should be 1 - x²/2.    B41:  (x - x³/6) should be x - x³/6. 
Section 4.2, page 204, Example 1, line 3 should be x = (c - b)/m (with the "x = " not above the division line.)
Section 4.4, page 238, Example 18: "A" and "B" are switched in the solution (but the answer is still right). It says "Let Pizza A be, say, a 10-inch pizza" when it should say "Let the smaller pizza be a 10-inch pizza" (B), and then A would be a 13-inch pizza.
Section 4.4, page 243, last offset line:  "$50,000 +" should not be in the numerator, but in front.
Section 4.6, page 278, A4(E): "Eliminate a F common" has an intrusive "F" by accident. Cross it out.
Section 5.1, page 295, A15 says "log(50) = 1.669" and should say "log 50 = 1.699."
Section 5.2, page 307, two lines below (5-2-8).  2-3 should be 2.3
Section 5.2, page 310, B35 has "will" twice in the last sentence. Delete the second occurrence.
                    page 311, B51: "Example 15" should be "Example 16"
Section 5.3, page 316, second line:  5-3-1 should be 5-3-3
                   page 316, line 8:  "Problem B18" should be "Problem B22"
Section 6.2, page 362, B4:  "x" should be "cos x"
Section 6.4, page 385, at the top the square root symbol should be extended to cover all of "9 - x²" (twice, line 1 and line 2).
Section 7.2, page 419, B22:  replace 90� with  π/2
                    page 420, B35, part D:  " in terms of csc θ" alone  [csc instead of sec]
Section 7.3, page 432, B54, part B:  "and use the using"  should be "and using" [delete "use the"]
                                    B55, part A:  7-1-3C should be 7-3-1C
Section 7.4, page 442, (7-4-5):  "for any B and C" should be "for any B and p"
                    page 442, Example 15, line 2:  "we need of wave" should be "we need a wave"
                    page 444, B16:  7-3-B69 should be 7-3B65            

Minor (These are typos, but it probably won't matter if you don't correct these): 
Section 4.1, page 201, above HW A5, after "appearance of 'x'", insert "assuming x ≠ 0"
Section 4.5, page 253. The graph in Figure 4 is a little off. (0,-3) should be the y-intercept. The figure has  (0,-2).
Section 4.6, page 266:  line two is missing a period at the end of "x-axis."
Section 5.4, page 324, Table 5-4-3:  the "distance" and "time" labels should be centered above their columns.
Section 7.2, page 420, B30: "d)" should be "D)", and it should be on the next line.
Section 7.3, page 433, B73:  "angle opposite"  should be "angle θ opposite" 
 
Solution manual:
Section 3.2, A23, manual page 17:  the partial answer in the text is right, but the solution in the manual should be -0.54 and 5.5.
Section 3.2, B41, manual page 18:  "Example 8" should be "Example 11"
Section 3.4, B25, manual page 21:  last factor should be (x² + 4), not (x² - 4)
Section 3.5, B19, manual page 23:  Change all three appearances of 5 to 5²
Section 4.2, A55, manual page 32, "Use 4.4.10" should be "4.4.11."
Section 6.2, B69, manual page 45:  The manual uses sin, but you could use tan, which might be better, depending upon where you measure the 24 inches. They yield very similar answers.
Section 6.2, B101B, manual page 46. It says "sin^-1 is one to one ...." and should say "sin is one to one...." The domain for sin is the range of sin^-1.
Section 6.4, B9, manual page 48:  [The answer is right but the expression for cos(BAC) should be cos(BAC) = (18² - 20² - 2.6²)/(-2(20)2.6) ]
Section 6.4, B27, manual page 50:  the angle labeled 17 should be labeled 20
Section 7.1, B5, manual page 51:  "Figure 9" should be "Figure 10"
Section 7.2, B23, manual page 23:  change the final step from "-tan θ" to "-1/tan θ".
Section 7.3, B65, manual page 57:  change 7.2.17 to 7.3.3A
Section 7.3, B67, manual page 57: [The work and steps are right. Delete the reference to B21.]
Section 7.4, B15, manual page 59:  change "65" to "66".
Section 7.4, B25, manual page 59:  [The answer is right, but the third last line has "70 + a" which should be "50 + a" and "16" which should be "70"
Section 7.3, page 57: The given solution to "B59" does not answer the question. It is, by accident, really a repeat the proof on pages 428-9. So, B59 is not answered.
