3 | 8/31/2011 9:46:17 | Laura Taalman | 5.1 | 12 | Problem 32 | This has a variable so will not be a "value". Change problem to some other fun thing like 2^{1 + 3 \log_2 1} | x |

4 | 8/31/2011 21:00:33 | Elizabeth Williams | 5.1 | 7 | Solution to problem (b) in Example 4. | It says log sub 6 3 is the exponent to which we would have to raise 6 to get 2, but it is supposed to be the exponent to which we would have to raise 6 to get 3. | x |

6 | 9/1/2011 22:53:46 | Irene | 5.1 | 10 | Typo for answer to problem 1 | it just says xxxxxx | x |

7 | 9/6/2011 11:06:28 | Allison Welborn | 5.3 | 30 | Example 2, Solution a. | It says to use the product rule in the third step to take the derivative but they use a minus sign instead of a plus sign. | x |

8 | 9/6/2011 15:57:23 | Alex Jusell | 5.4 | 41 | In the chart on the top half of the page | The wrong number is used in the "every minute" row and the "times compounded" column. It should be compounded 525,600 times, not 1,314,000 times. | x |

9 | 9/6/2011 20:28:27 | Nicole Price | 5.3 | 29 | Solution to Example 1c | The first sentence ends with a parenthesis even though there was no other parenthesis in the sentence. | x |

16 | 9/15/2011 9:33:55 | Kate Reiman | 5.5 | 59 | Problem 67 | You said if the problem were changed to lim as x->infinity (1/2)^x(x^100) it would be a better problem. | x |

17 | 9/16/2011 10:29:24 | Amanda Wright | 6.1 answers | 3rd page of answers | Bottom left column of answers | #47 should be(-sqrt2/2,-sqrt2/2) #73 doesn't have an answer, should be 2pi/3k | x |

18 | 9/17/2011 16:42:41 | Dorottya Boisen | Chapter 5 review | No pg#, but would be pg62 | Limits of Exponential and Logarithmic functions | "If k>0, then lim as x approaches negative infinity of e^(-kx)" is written twice.

20 | 9/19/2011 17:58:34 | Dorottya Boisen | 6.2 | 82 | Proof of Theorem 6.6 | Unit circle shows angle theta and -theta. The x and y co-ordinates for angle -theta should both be negative. Currently it is (x, -y), but the lower left quadrant has negative values for both x and y, so it should be (-x,-y). | x |

21 | 9/21/2011 17:18:41 | Anne Hurst | 6.3 | 92 | third paragraph, third sentence. | it says " Now by applying the Squeeze Theorem the the double inequality...." there should only be one "the." | x |

22 | 9/22/2011 10:29:08 | Mason Moomaw | 6.2 | 85 | Last sentence in the answer to example 2. | The solution shows that the answer is -f(x), making it an odd function. But in the next sentence it says "since f(-x)=f(x) for all values of x in its domain, we can say that f(x) is odd." It should say, "Since f(-x)= -f(x) for all values of x in its domain, we can say that f(x) is odd. | x |

23 | 9/22/2011 18:12:21 | Alex Smyth | 6.2 # 61 and 63 Answers | p. 89 | second column half way down the page | The Answer for # 61 and 63 is blank | x |

24 | 9/22/2011 19:57:10 | Maile Wood | 5.4 | 41 | In the table of compounding interest | shouldn't the last column be titled "balance after 5 years"? t seems to be 5 in each example as in every other example given up to that point. | x |

25 | 9/22/2011 21:15:54 | Alex Smyth | 6.2 | 85 | fourth line. | The book shows that sin(pi/4)cos(pi/6)-sin(pi/6)cos(pi/4) = (sqrt2/2)(sqrt3/2)-(1/2)(1/sqrt2) I believe the (1/sqrt2) should be sqrt2/2 because cos(pi/4)=sqrt2/2 | x |

26 | 9/22/2011 22:11:01 | Alex Smyth | 6.2 | 85 | Solution for example 2 | The last line says that Since f(-x) = f(x) then f(x) is odd. The negative sign is missing from the f(x) | x |

27 | 9/28/2011 15:09:12 | SaraKate Rohloff | Answers of 7.1 | Back of the book | Answer to number 33, the second line. | two addition signs "0.18166+ +0.18439" | x |

31 | 10/9/2011 21:00:44 | Anne Hurst | 7.4 | 161 | the last sentence of the first paragraph. | It says "In such cases will have to split up the interval....." It should say "In such cases we will have to split up the interval...." | x |

33 | 10/10/2011 9:53:35 | Isabelle Masters | 7.4 | 159 | last sentence of the second paragraph | One of the numbers in the Left Sum equation is missing a decimal point. It says "01875" but it should be "0.1875". | x |

34 | 10/13/2011 20:46:33 | Evan Bryant | 7.4 | 167 | Problem number 5, fourth and fifth line | The error is "Will the unsigned are will be positive or negative, and why? Will the signed area will be positive or negative, and why?" and it should read, "Will the signed/unsigned area be positive or negative, and why?" | x |

35 | 10/13/2011 20:49:59 | Varqa Tavangar | 5.1 | 8 | Solution to Example 6(a) | in the third line, y-axis should be x-axis. | x |

38 | 11/2/2011 21:44:27 | Dorottya Boisen | 9.3 | 256 | Example under Theorem 9.13 about completing the square | Text says that quadratic function x^2 + 6x + 10 has b=4, but b=6. | x |

41 | 11/7/2011 10:03:36 | Maile Wood | 9.4 | 268 | In the table of rewritten forms and u substitutions | In the first example under the choose category: it says "u = cos x, du = sin x dx" but it should say "du = -sin x dx" | x |

42 | 11/7/2011 10:10:00 | Maile Wood | 9.4 | 268 | In the table of rewritten forms and u substitutions | In the second and third examples under the choose category: "dx" is missing at the end of the du. | x |

43 | 11/9/2011 20:45:22 | Dorottya Boisen | Answers to 9.4 | no page number | answer to question 41 | answer should be 1/4x - 1/8x - 1/96 sin 12x + C | x |

44 | 11/9/2011 21:02:49 | Dorottya Boisen | 9.4 Answers | no page number | Answer to question 35- suggestion | Book says to use parts with u= csc^2 x and dv= csc^2 x dx, the use u substitution later. It is much simpler (and more intuitive) to split the integrand into (csc^2 x) (csc^2 x), then re-write as (csc^2 x) (1+ cot^2 x), then use u substitution where u= cotx and du= -csc^2 x dx. | x |

48 | 12/1/2011 23:56:10 | Ethan Blackwell | 10.1 | 314 | Definition 10.2 second sentence. | Just a typo, it says "given by a continuous funtion r=r(x) on [a,b]" the correction is just to put the c in function. | x |
