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.
