Course description

Real numbers; coordinate systems; functions; limits and continuity; differentiation and applications; trigonometric functions; indefinite and definite integration and applications; fundamental theorem of integral calculus. Usually offered every term. Prerequisite: MATH-170 or four years of high school mathematics. Note: Students may not receive credit toward a degree for both MATH-221 and MATH-211.
The overall objectives of this course are to
  1. Examine the unique role of the concepts of derivative and integral in the quantification of change. In so doing, students will be able to explain how any quantitative method involving the measurement of change inevitably leads to these concepts.
  2. Develop quantitative facility with the computational aspects of this theory, with a strong view towards their application, both inside and outside mathematics.
  3. Nurture student comfort in mathematical language, discourse, and thought.

Homeworks

You must staple your assignments before submission; points will be deducted otherwise! Homeworks are due on the dates listed, to be turned in at the beginning of lecture. If you think that you need more practice, just ask! I'll be happy to give you more problems to work, and will also be happy to answer questions about them.

Course policies

A typical course meeting

On most non-exam days, there is a usual cadence to the classes, which goes something like this...
  1. At the beginning, I will take attendence
  2. I will either give you a quick quiz or select students to present specific problems (which I choose) from the homework that pertain to the section covered in the previous class. (Come prepared to at least attempt all the problems!) If you have trouble articulating your solution (or you get stuck), that's OK! The rest of the class and I will help you!
  3. I will present the new section. Taking notes and asking questions is encouraged!
  4. Depending on the nature of the material, we will walk through some representative problems afterwards, either as a class, or in smaller groups.

Absences

You are expected to attend all the class meetings. I will take attendence, usually as roll call at the beginning of class. There may be unexpected quizzes, and you may not take these at a different time! Please contact me in advance if you cannot attend (this includes both religious observances as well as sporting obligations), especially in the case of an exam. Missing an exam without appropriate (prior in all but a few situations) authorization is cause for a zero on that exam!

Late homeworks are not accepted without a University-approved excuse. You have the schedule in front of you now; turn assignments in early if you plan to be absent.

Exams

For each exam, you will be permitted to bring one double sided hand written 8.5 x 11 sheet with handwritten notes on it. Electronic calculators will not be permitted. However, mechanical calculators (such as this or these) are fine.
Missing an exam without appropriate (prior in all but a few situations) authorization is cause for a zero on that exam!

Grading

The course grade will be determined from the following components. You'll accumulate points for each of these over the course of the semester.
10% Homework
20% Exam 1
20% Exam 2
20% Exam 3
30% Final exam

Here's how to associate letter grade equivalents to the percentage of points you've gotten (weighted as above):
A = 93 or above
A- = 88 to 92.9 < Minimum grade to be recommended as a tutor!
B+ = 85 to 87.9
B = 82 to 84.9
B- = 78 to 81.9
C+ = 75 to 77.9
C = 72 to 74.9
C- = 68 to 71.9
D = 60 to 67.9
F = below 60

Academic dishonesty

Academic dishonesty is a serious offense. Read our University policies. As applied to this course, you may work together on homeworks, but the work you turn in must be your own. I'm happy to answer any questions you have about these policies.
