## Announcements

#### Homework 3

The third written homework assignment is due this Friday, September 29. Here is the assignment:

You should feel free to work together with other students on the assignment, but everyone must turn in their own copy of the solutions, and you must acknowledge any collaborators. I will be having office hours this Thursday and Friday to help with the homework.

#### Quiz 3 Tuesday

The third quiz is next Tuesday, September 26. It will cover partial derivatives. See the practice problems below.

#### Practice Problems: Partial Derivatives

Here are some practice problems on partial derivatives:

- Section 11.3 # 3, 15, 17, 19, 21, 23, 25, 27, 39
- Section 11.4 # 1, 3, 5, 17

Answers can be found in the back of the book.

#### Homework 2

The second written homework assignment is due this Friday, September 22. Here is the assignment:

You should feel free to work together with other students on the assignment, but everyone must turn in their own copy of the solutions, and you must acknowledge any collaborators. I will be having office hours this Thursday and Friday to help with the homework.

#### Quiz 2 Tuesday

The second quiz is next Tuesday, September 19. It will cover cross-sections, contour plots, and equations of planes. See the practice problems below.

#### Practice Problems: Equations of Planes

Since the book doesn't cover equations of planes very well, I've written some brief notes on the subject as well as some practice problems.

The answers to the exercises are on the second page of the PDF.

#### Practice Problems: Cross-Sections and Contour Plots

Here are some practice problems on cross-sections:

- Section 9.6 # 18 (answer)
- Section 11.1 # 9, 11, 14 (answer), 19, 23, 35, 37, 45

Answers to the odd-numberd problems can be found in the back of the book.

#### Homework 1

The first written homework assignment is due this Friday, September 15. Here is the assignment:

You should feel free to work together with other students on the assignment, but everyone must turn in their own copy of the solutions, and you must acknowledge any collaborators. I will be having office hours this Thursday and Friday to help with the homework.

#### Cross-Sections Animation

Here is the animation of cross sections that I showed in class yesterday:

#### Quiz 1 Solutions

The first quiz was on Tuesday, September 12. It covered derivatives (see Chapter 3) and multivariable functions (Section 9.6). Here are the solutions:

#### Practice Problems: Multivariable Functions

Here are some practice problems on multivariable functions:

- Section 9.6 # 9, 13, 15, 23

Answers to these problems can be found in the back of the textbook.

#### Reading

Please read sections 9.6 and 11.1, and 11.3 before next Tuesday's class.

#### Derivative Practice Problems

Here are some practice problems on basic derivatives. They are from the Chapter 3 Review on pg. 248. (The exercises start at the bottom, after the “Concept Check” and the True-False Quiz.)

- Chapter 3 Review Exercises: 1, 3, 5, 7, 9, 11, 17, 25, 27, 31, 41

Answers to these problems can be found in the back of the textbook. If you have trouble with any of these problems, you might want to try watching some of the review videos listed below.

#### Welcome!

Welcome to Math 142. I will be using this course webpage to post all announcements and documents, including homework assignments, homework solutions, and practice exams.

## Textbook Information

The textbook is

*Calculus: Concepts and Contexts, 4th edition* by James Stewart. You will need a copy of the textbook for reading and homework problems, though you do not need to bring it to class. An electronic version of the book can be

rented for $24 from the publisher, or you can

buy the Kindle version for $105 from Amazon.com. You can also

rent a hardcover version from Amazon.com for $90.

## Course Policies

#### Introduction

Math 142, second-semester calclus, will continue to explore the fundamental ideas of differentiation and integration that you learned in Calculus I. Topics to be covered include functions of several variables, partial derivatives, integrals of single-variable functions, techniques of integration, improper integrals, applications of integration, and multiple integrals.

#### Prerequisites

This course is designed for students who have completed Calculus I (Math 141), or who have taken a calculus course in high school. We will be assuming basic knowledge of derivatives (including the product rule and chain rule) and integrals.

#### Textbook

The text is

*Calculus: Concepts and Contexts*, 4th edition, by James Stewart. We will cover most of the material in chapters 5, 6, 11, and 12, as well as a few topics from elsewhere in the text. You are encouraged to read the text

*before* coming to class, and then again while doing the homework.

#### Written Homework

There will be a weekly written homework assignment due each Friday consisting of a few longer problems, with an emphasis on the conceptual side of calculus. You are encouraged to work with other students in solving the homework problems, but you should write your own solutions, and you must acknowledge anyone that you work with. Your solutions should be written clearly and in complete sentences, with enough detail that another student in the class would be able to follow your reasoning.

#### Practice Problems and Quizzes

Computation is an important component of mathematics, and is a key part of any calculus course. I will often recommend practice problems from the textbook, and you are strongly advised to try at least some of these problems. To make sure your computational skills are progressing, there will be a short (10–20 min.) quiz each Tuesday consisting of a few relatively straightforward computational problems.

#### Exams and Grading

The grade will be based on the weekly homework, quizzes, the midterm exam, and the final exam:

Written Homework | 25% |

Quizzes | 25% |

Midterm Exam | 25% |

Final Exam | 25% |

The midterm exam is two hours long, and will be offered on **Friday, October 27**. The final exam is two hours long, and will be on **Thursday, December 21**.

#### Calculator

You will need a calculator for the quizzes and the exams. Any calculator is permitted, and even a scientific calculator app on a smartphone would suffice.
