Math 140B: Elementary Analysis (Fall 2019)

Lectures

• Lecture 44783 meets on MWF at 1:00-1:50 PM in RH114.

Some important information:

• I will have office hours on Mondays and Wednesdays in Rowland Hall 440G from 2:00-2:50 PM.
• If you email me, please always put the course number 140B in the subject line, or I might miss your email.
• If anyone is spotted browsing the internet or sending text messages during lectures, their computer or cell phone will be confiscated for the remainder of the lecture. However, taking notes on a tablet PC, or briefly using a computer to look up a formula is acceptable (except on an exam of course).
• It is acceptable to form study groups and discuss homework with other students, but you must write up your own solutions individually. Do NOT just copy solutions from someone else or from the internet (we have access to the internet too, and can easily spot if a solution was just copied from an internet source).
• Cheating is not allowed, and will result in very serious consequences if you are caught.

Examinations, Homework, Quizzes, and Final Grade

• There will be weekly homework assignments, 2 in-class exams, weekly quizzes in discussion, and a final exam.
• Quizzes: 15%, Homework: 15%, Exam I: 20%, Exam II: 20%, Final: 30%. Cutoff for A = 90, cutoff for B = 80, cutoff for C = 70, cutoff for D = 60, and below 60 is failing.
• The in-class exams are scheduled for October 25, November 22. The final exam is on December 11. There are no make-up exams. Exams may not be missed or rescheduled, except with a note from the dean. (With a valid note, the weight of the exam missed will be added to the weight of the final exam.)
• Homework is due at the beginning of discussion on Thursdays, unless otherwise noted. No late homework will be accepted.
• Quizzes will be in discussion on Tuesdays, except for the first week and the 2 weeks with an exam. There are no make-up quizzes.
