Course Description

This course is devoted to the elementary theory of Fourier series and the Fourier transform; We will primarily cover chapters 1-6, with material from later chapters and forays outside of the textbook as time permits. This course is proof-based.  Prerequisites: Recommended: Calculus III, Linear Algebra. 110.405 or 110.415.


Homework assignments will be announced in the lecture and posted in the page of Schedule and Homework, roughly on every Thursday and will be due on the following Thursday. Please make sure  put your homework # and your name on the top of your paper and staple your homework. Late homework will not be accepted.  Homework submitted not on time will receive a grade of 0. There are about 10 homework assignments in total.

Sufficient practice in the homework is essential to master the material, so it is highly recommended to try to complete every assignment. You are permitted, perhaps encouraged, to discuss homework problems with other students. This collaboration should not extend to the process of writing up solutions. The work that you turn in should be written by you, in your own words, without supervision or other well-meaning influence from anyone else.

Exam Policy

There will be one in-class midterm exams scheduled on Oct 26 and a take-home final exam due on Dec 14 12:00pm.

You are expected to attend class and take exams as they are scheduled. If you have time conflicts with an exam or need special arrangements, you must notify the instructor in writing at least one week in advance. There will be no makeup exams; if you miss an exam with a valid excuse (with documents from either the Office of Student Life and/or doctors), then your grade for the missing exam will be the weighted average of your other grades.

Grading Policy

The grade for this course will be determined as follows. 

• Homework: 30%

• Midterm Exam: 30%

• Final Exam: 40% 

Ethics Statements

Cheating is wrong. Cheating hurts our community by undermining academic integrity, creating mistrust, and fostering unfair competition. The university will punish cheaters with failure on an assignment, failure in a course, permanent transcript notation, suspension, and/or expulsion. Offenses may be reported to medical, law, or other professional or graduate schools when a cheater applies. Violations can include cheating on exams, plagiarism, reuse of assignments without  permission, improper use of the Internet and electronic devices unauthorized collaboration, alteration of graded assignments, forgery and falsification, lying, facilitating academic dishonesty, and unfair competition. Ignorance of these rules is not an excuse.

In this course you may collaborate with other students while attempting to solve homework problems, but only under the guidelines described above. Your work on any exam, whether in class or take-home, must be entirely your own. If you are having difficulty with a particular exam question, it is permissible to ask the instructor (but no-one else) for clarification.  The strength of the university depends on academic and personal integrity. In this course, you must be honest and truthful. See the guide on "Academic Ethics for Undergraduates" and the Ethics Board Web Site for more information.
