12/01/01  Second Midterm Locations: For the midterm this Monday, please take the exam in the following lecture halls depending on what class you are in: If you are in Huan Yang's or Dmitry Tamarkin's class, please go to Science Center A to take the exam. If you are in Pete Clark's, Alina Marian's, or a MWF class, please go to Science Center C to take the exam. 
11/21/01  Second Midterm Review Material: Here are some past exams for you to look at as practice for the upcoming second miterm. Because of the changes in course structure this year, some of the past exam questions may not be pertinent for our Second Midterm. Relevant questions are noted following each exam link (Note: The relevent questions are now accurate for each exam): Fall 1990 Exam 3 (Relevant questions: Part I #14 and Part II #1); Fall 1998 Exam 2 (Relevant questions: 1b, 2, 57); Spring 1999 Exam 2 (Relevant questions: 13, 4ab, & 7); Nonrelevant problems are included so that you can use them to review for the final exam in January. Also, here are the solutions to the above exams: Fall 1990; Fall 1998; Spring 1999 
11/16/01  Technique Test Retest There have been a handful of additions and corrections made to the integral practice problems and solutions. Please use these materials for the retest, which is on this coming Tuesday. 
11/15/01  Course Materials Future homework assignments will come out of the handout received in class and a supplementary packet, in addition to the textbook. The supplement can be purchased at the Gnomen Copy on Mass Ave. across from Widener Library for about $3.00. This charge is simply to cover the cost of reproducing each book. 
11/06/01  Technique Test Prep IV Here are some corrections on the solutions. Good Luck on the Test! 
11/03/01  Technique Test Prep III The integral problems handout has been updated with a few additional problems and corrections to problems 22 and 32  just go to the link listed in the 10/31 announcement to take a look. Here are the solutions; there may be a few errors remaining, but they should be accurate for the most part. If anyone comes across what they feel like is an error, please email me. 
10/31/01  Technique
Test Preparation Here is a list of integral problems from which at least 70% of the technique test questions will be chosen. Please check back on Friday in case there are additional problems posted or other changes. Solutions will be posted by Friday as well. 
10/27/01  Simpson's Rule as a
Weighted Average Please take a look at this handout that deals with Simpson's Rule.

Course Information 
Course Content and Goals: About four hundred years ago, Galileo wrote
Although the language of mathematics has evolved over time, the statement has as much validity today as it did when it was written. In Mathematics 1b you will become more wellversed in the language of modern mathematics and learn about its applications to other disciplines. Math 1b is a second semester calculus course for students who have previously been introduced to the basic ideas of differential and integral calculus. Over the semester we will study three (related) topics, topics that form a central part of the language of modern science:
We will start the semester by studying infinite sums. You already are aware that a rational number such as can be represented by an infinite sum, ( , for the case at hand). Actually, irrational numbers such as e and have representations as infinite sums as well. In fact, we will find that many functions, such as and can be represented by infinite polynomials known as power series. Polynomial approximations based on these power series representations are widely used by engineers, physicists, and many other scientists. In your previous math courses you may have seen functions represented by integrals. For example, can be represented by . Integrals can be used in many contexts. The definite integral enables us to tackle many problems, including determining the net change in amount given a varying density. In the second unit of the course we will revisit integration. First we'll study the integration analogues of both the Product Rule and Chain Rule for differentiation and briefly touch on some alternative transformations of integrals that enable us to tackle them more efficiently. The goal is not to transform you into an integration automaton (we live in the computer age), but to have you acquire familiarity with the techniques and the ability to apply them to some standard situations. More important is the ability to apply the integration as appropriate in problem solving; we will devote time to developing your skill in doing this. We will end with differential equations, equations modeling rates of change. Differential equations permeate quantitative analysis throughout the sciences (in physics, chemistry, biology, enviromental science, astronomy) and social sciences. In a beautiful and succinct way they provide a wealth of information. By the end of the course you will appreciate the power and usefulness differential equations and you will see how the work we have done with both series and integration comes into play in analyzing their solutions.

Homework: An assignment will be given at each class meeting. Unless otherwise specified, the assignment is due at the following class meeting and will be returned, graded, at the subsequent class. If you miss a class, then you are responsible for obtaining the assignment and handing it in on time. Solutions put together by the course assistants will be available on the course website. When your homework assignments are returned to you, you can consult the solutions for help with any mistakes you might have made. Problem sets must be turned in on time. When computing your final homework grade, your lowest two homework scores will be dropped if you are in a TTh section and your lowest three homework scores will be dropped if you are in a MWF section. Note that homework problems will sometimes look a bit different from problems specifically explicitly discussed in class. To do mathematics you need to think about the material, not simply follow recipes. (Following preset recipes is something computers are great at. We want you to be able to do more than this.) Giving you problems different from those done in class is consistent with our goal of teaching you the art of applying ideas of integration and differentiation to different contexts. Feel free to use a calculator or computer to check or investigate problems for homework. However, an answer with the explanation `` because my calculator says so" will not receive credit. Use the calculator as a learning tool, not as a crutch. Calculators will not be allowed on examinations due in part to equity issues. You are welcome to collaborate with other students on solving homework problems; in fact, you are encouraged to do so, and we will provided you with contact information for your classmates in order to faciliate that. However, writeups you hand in must be your own work, you must be comfortable explaining what you have written, and there must be a written acknowledgement of collaboration with the names of you coworkers. Oddnumbered problems are solved in the Student Solution Manual; some coies will be put on reserve in the Cabot Science Library. After working on the problems on your own, you are free to consult this manual provided you acknowledge the use of this manual in your submitted work. (This is a standard rule of ethics.)
Exams:
There will be an optional Technique reTest available on Tues. Nov. 20th: 7:30  8:30 in SC C. The higher of your two scores counts in the computation of your course grade. The first test is not optional. Calculators will not be allowed on examinations, due in part to equity issues. We will make sure that problems on the exams require minimal calculation to allow you to spend your time demostrating your mathematical knowledge as opposed to your calculating ability. We expect you to express your ideas, line of reasoning, and answers clearly.
Grading Policy: Your course grade will be determined as follows:
Sources of Academic Support: A schedule of all Math 1b problem sessions will be posted on the course website. You are welcome to go to any and as many problem sessions as you like.
