Page | Description | Date |

p 12, line 6 | Planes listed are yz, xz, and yz instead of yz, xz, and xy | 10 Jan 2022 |

p 17-18, example 1.3.5 | xyz was set equal to 1 instead of 4 several times | 15 Jan 2022 |

p 26, top | Image doesn't show in some viewers | 19 March 2022 |

p 190, example 3.7.5 | t= instead of t-> | |

p. 47, example 2.3.10 | Diagram missing from first box | 4 Feb 2022 |

Section 3.1.4, Surplus | The interpretation of the area between the curves works better if we say that the demand is over number of consumers: one person would buy the thing at this price, two people would buy it at this price. One supplier can produce a thing for $1 each, another supplier can produce a thing for $2 each. | 27 Jan 2022 |

p 220 | Steady state is r/k, not k/r | 24 March 2022 |

p. 249, exmple 4.2.9 | Table uses x instead of X | 6 March 2022 |

p. 255 ex 4.3.5 | 1/20 and 1/30 should be 2/10 and 3/10 | 19 March 2022 |

p. 316/317 ex 5.3.4 | p316 integral should start at 2; p317 Integral should start at 1, not at 2. Upper bound of sum is 2, not 3/2. | 1 April 2022 |

p. 327 ex 5.3.8 | "the integral" repeated | |

Def 6.3.2 p 351 | missing criteria for taylor series to converge *to* a function | 2 April 2022 |

ex 6.4.5 p 362 | Improved bound uses n=2, not n=2 |

p 16 etc, Section 2.2, Q 9 | Partial derivatives of utility functions should go to 0 as the quantities go to infinity; there are issues with wording in the question, and significant issues with the solution, including taking limits and partial derivatives. | 26 Feb 2022 |

p 106, Section 4.6, Q13 | Description of function is missing half the x-bounds | 13 March 2022 |

352, Section 2.6 Q 4, others | Gradient notation is used in several problem solutions, but we removed gradient from the text | 19 Jan 2022 |

p 362 Q 12 section 2.6 | In the current version, this quesiton is very flawed, and should be ignored. Extremum at endpoint. Sign error affects normality / inferiority; also need to check endpoints, more chicken makes you less happy. Should say that we can assume we have enough money to buy the minimum. | 19 March 2022 |

375, Section 3.1 q. 8b | 5^3 is 125, not 225 | 16 Jan 2022 |

p. 566, Section 4.6, solution 10 | F(1) should be F(0) in one place; "o.e."" should be "i.e." | 1 April 2022 |

590, Section 5.1 q. 36 solution | Last term of line of page should have 3 in denominator, not 8 | 13 March 2022 |
