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 364, 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 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.
