Course Description

Math 121 is designed for students who have completed a high school calculus course and who might pursue study in an area for which calculus is an essential tool, but who are not prepared to place out of calculus. This course is a deeper and broader study of calculus than Math 117; theoretical aspects are not the main focus but will not be avoided. The course will, together with Math 122, treat limits, derivatives, and integrals; the calculus of exponential, logarithmic, trigonometric, and inverse trigonometric functions; techniques of integration; plane analytic geometry; various applications of calculus; sequences and series, including power series and intervals of convergence.


Homework is an important part of any math class. It is important that you practice doing the problems. This will help you to understand the material better and will prepare you for the exams. You are encouraged to discuss the homework, and to work together on the problems. However each student is responsible for the final preparation of his or her own homework papers.

Homework will be assigned at the end of every class. It will also be posted on the website:

It is due the following class. If for some reason you miss class or cannot turn in the homework during class, you have until 4pm that day to put it in your TA's mailbox. After that time, late homework will not be accepted.


Technology, such as the software package Mathematica, can be a useful tool when learning mathematics. Although technology will not be emphasized in this class, I will occasionally use Mathematica during lectures.

Some of the homework problems that I will assign will require some technology. I recommend using Mathematica, which is available in the computer labs on campus. It is also available for download at However, if you prefer to use (and know how to use) another software package or device such as a graphing calculator instead, you should feel free to do so. I do not recommend buying a graphing calculator solely for the purpose of this class.

Although technology can be a useful tool, it is important that you do not become depend on it. For this reason (as well as some logistical reasons), you may not use calculators during exams.


Two midterms and a final will be given.

  • Midterm 1 - Thursday, October 11
  • Midterm 2 - Thursday, November 15
  • Final - Tuesday, December 18, 2:00-5:00pm

  • Course Grade Determination

    The course grade will be computed as follows:

  • Homework - 20%
  • Midterm 1 - 25%
  • Midterm 2 - 25%
  • Final - 30%
  • There will be two extra credit projects assigned during the semester. These can increase your course grade.

    The first one can be found here. It is due Thursday, October 18. This can increase your final course grade up to 3 percentage points.

    The second one is Project 5.5 in the book (p. 266-268). It is due Tuesday, December 4. This can also increase your final course grade up to 3 percentage points.

    Office Hours

    Sometimes it is helpful to have one-on-one conversations, which is not really possible during the scheduled class time. This is the purpose of office hours. Office hours are times that I have set aside in my schedule to be available to you. This gives you the opportunity to ask questions about something you didn't understand the in the lecture or a homework problem. Please take advantage of this time.

    I will hold office hours Mondays 4-5pm and Wednesdays 3-4pm. If you cannot make these, feel free to email me at to make an appointment for a different time.

    The Math Workshop

    The Math Workshop, x2205, is located in Room 113A Science Center, in other words in the Main floor Conference Room in the Science Library. It is open Sunday through Thursday from 7 to 10 pm and Monday through Thursday from 2:30 to 5 pm during the semester. There are always two staff members on duty, who may be either experienced undergraduates or math graduate students. This is a drop-in tutoring service, available to all members of the Wesleyan community. Staff members provide a friendly, relaxed atmosphere while answering questions about mathematics. The workshop is a good place to go when you get stuck on your math homework.

    Students with Disabilites

    It is the policy of Wesleyan University to provide reasonable accommodations to students with documented disabilities. Students, however, are responsible for registering with Disabilities Services, in addition to making requests known to me in a timely manner. If you require accommodations in this class, please make an appointment with me during the first two weeks of class, so that appropriate arrangements can be made. All discussions will remain confidential. Students with disabilities should also contact Dean Lazare. Please see for more information.
