Text Calculus, Concepts and Contexts, 4th edition, Stewart.

We will cover roughly Chapters 2, 3 and 4. You can probably use a different book, possibly much cheaper. All homework will be on WeBWorK or handouts, so nothing will be assigned by problem number in the book. You may be able to use an earlier edition of the book, or maybe even a book by a different author, as long as you use a book intended for scientists and engineers (texts on calculus for business and social science students will not do) and can match the material in the course to the appropriate sections in the book.

Class Meeting Monday and Wednesday 6-8pm, 105 Fenton Hall.

Prerequisite MATH 112 or satisfactory placement test score.

Calculators Calculators may be helpful for homework, but is both NOT necessary and NOT allowed for exams.

Exam Policies

All exams are cumulative, although they will usually emphasize the most recent material. All exams will cover material through the most recently turned in homework. No calculators or other electronic devices will be permitted on any exam.

At least 80% of the points on each of Midterms 1 and 2 will be based on homework problems, on problems on separate supplementary lists.

Complaints about the grading of any exam must be submitted in writing by the beginning of the first class period after the class in which that exam is returned.

Approximate Schedule (subject to change)

Homework

There will be two kinds of homework: written homework and WeBWorK homework. You are encouraged to discuss homework problems with each other, but you need to submit your own work and make sure you understand it.

Week 1 written homework is available here.

Paper assignments will be turned in to me at the beginning of the class period in which they are due. Normally the handouts will be distributed on Wednesday during class and due the following Monday. Some instructions:

• Staple pages together. Don't fold or tear corners or fold in half.
• If you cooperate with someone else, that person's name must appear below yours.
• Simplify all answers.
• Show your work. Otherwise you will not get credit.

WeBWorK

Assignments using WeBWorK will be done on the internet, here. The assignments for week N will be due on Thursday 11:59pm next week, i.e. Week N+1.

Some warnings:

• Variables are case sensitive.
• Some notation used in WeBWorK is artificial, and is not correct in written work. (For example, since "DNE" is not a number, expressions such as "lim ... = DNE" are meaningless.)
• Read the instructions for each problem separately! Different problems were written by different people. For example, sometimes infinity is supposed to be "INF" and sometimes "infinity". Problems requiring notation for intervals, units, or other uncommon notation are supposed to have links to instructions, but not all of them do. General instructions for entering the kinds of sets likely to arise as domains and ranges are here. It doesn't seem to be in the practice assignment, but the square root of x can be entered as "sqrt (x)". Also, "x^(1/2)" gives x to the 1/2 power, which is the same thing.
• The number of attempts allowed on a question may vary.

Learning Objectives The single largest course goal is:

• A successful student in this course should be able to model and solve a wide class of optimization (maximization and minimization) problems that are accessible to differential calculus. Solving such a problem includes providing, without being explicitly asked to, mathematical justification that the supposed solution really is a maximum or minimum, as appropriate.

Much of the other material covered in this course is necessary for that objective. So subgoals include:

• Be able to differentiate elementary functions (the kind seen in precalculus courses). This is necessary to use calculus to solve optimization problems (or any other kind of problem---see the additional objectives below).
• Demonstrate understanding of the meaning and significance of the derivative of a function in the following ways:
  • Describe qualitative features of the behavior of a function (increasing, decreasing, relative maximums and minimums, etc.) based on various combinations of algebraic, numerical, and graphical information about its first and second derivatives.
  • Describe qualitative features of the behavior of the first and second derivatives of a function (positive, negative, increasing, decreasing, relative maximums and minimums, etc.) based on various combinations of algebraic, numerical, and graphical information about the function.
  • This is needed for sketching graphs (below) and locating local extremums when trying to optimize.
• Be able to sketch graphs of functions. This is necessary to help identify where to search for local and global extremums when trying to optimize.
• Understand some basic facts about limits. This is needed for two reasons: to incorporate an understanding of the geometric interpretation of the derivative as the slope of the tangent line of a graph, and also to aid in sketching graphs of functions exhibiting asymptotic or discontinuous behavior.

Learning Environment The University of Oregon strives for inclusive learning environments. Students who have a documented disability and anticipate needing accommodations in this course should see me as soon as possible. You are also encouraged to contact the Accessible Education Center in 164 Oregon Hall at 541-346-1155 or uoaec@uoregon.edu.

Academic Conduct The code of student conduct and community standards is at conduct.uoregon.edu. In this course, it is appropriate to help each other on homework as long as the work you are submitting is your own and you understand it. It is not appropriate to help each other on exams, to look at other students exams, or to bring unauthorized material to exams.
