Course Descritption:
Second course in a rigorous three-quarter sequence on real analysis. Topics include: differentiation, integration, sequences and series of functions, some special functions.

Textbook: Principles of Mathematical Analysis by Walter Rudin, 3rd edition. We will cover most of Chapters 5 through 8.

Additional Study Materials: (you will not be tested on these)

Lecture:
Lecture will occur live on Zoom (use meeting ID: 993 1607 8691 or navigate to https://ucsd.zoom.us/j/99316078691). Videos of our lectures will be posted on our Canvas page under the Media Gallery tab. Additionally, the Lecture Notes I write in class will be updated shortly after each lecture.

Community Interaction: Typically meeting in the classroom allows students the opportunity to get to know one another and discuss the course material together. Since class meetings will not occur, as a substitute we have a discussion forum on Piazza that everyone is encouraged to use. Our class piazza page is here: https://piazza.com/ucsd/winter2021/math140b.

Homework: Homework will be assigned regularly and due on Fridays at 9:00 PM. No late homework will be accepted. On each assignment, a few problems will be graded for correctness, while the others will be graded simply for completion. We will use Gradescope for turning in homework. When registering for gradescope, please register using your "@ucsd.edu" email address and use Entry Code YV7BE3.

Homework 1 (Due Friday Jan. 15): Chapter 5 problems 2, 4, 6, 8, 14, 19, 26 (Convex functions are defined in exercise 23, page 101)
Homework 2 (Due Friday Jan. 22): Chapter 5 problems 9, 11, 15, 17, 22 and Chapter 6 problems 1, 2, 4

Homework 3 (Due Friday Feb. 5): Chapter 6 problems 3, 5, 6, 7, 8, 10(abc), 11, 15 (use >= for the final inequality), 19
Homework 4 (Due Friday Feb. 12): Chapter 7 problems 1, 2, 3, 4, 5, 6, 8, 9, 14
Homework 5 (Due Friday Feb. 19): Chapter 7 problems 7, 10, 12, 13, 15, 16, 18, 19 (For #19, you can assume the truth of Ch. 2 problem 26)
Homework 6 (Due Friday March 5): Chapter 7 problems 20, 21, 23 and Chapter 8 problems 1, 4, 5, 6, 7 (you can use properties of trigonometric and exponential functions discussed in the book)
Homework 7 (Due Friday March 12): Chapter 8 problems 10, 11, 12, 13, 14, 22 (Only prove Newton's binomial theorem)

Exams: The midterm exams will be taken at home and solutions will be uploaded to Gradescope. The exams will be open-book and open-note, but the use of online resources and help from other humans is forbidden. If cheating is suspected, students will be required to have a one-on-one zoom meeting to solve similar problems. Students found to be cheating will receive a 0 on their exam.
Grading: Your final grade will be the maximum of the following two weighted averages:
Special Accommodations: Students requiring accommodations should provide an OSD letter of certification and OSD accommodation recommendation to me as soon as possible.
