This course concerns infinite sequences and series. These discrete objects could be used to approximate continuous objects such as functions and integrals that have been studied in 21-115, 21-116 and 21-117.

Latest news

• HW3 is complete.
  
  
• Unlike the first 2 hw assignments, HW3 is due on Friday, Aug. 9, 2002. So, start early!
  
  
• Final is coming up! It's in class on August 9(Friday), 2002. It covers Sec 11.8, 11.9, 11.10, 11.11(I decided not to skip this section) and 11.12. On August 8(Thursday), we'll have a review in class.
  
  
• HW2 is complete. It's due on Aug. 5(Mon), 2002.
  
• There will be a retest for the midterm for those who got lower than 75. The midterm grade will be updated by the following formula: midterm = min( max(midterm,retest), 75 ). The retest will be held in Wean Hall 6403 from 3:00 p.m. to 4:50 p.m. on Aug. 5, 2002 (Monday). There will be definitely NO retest for the final.
  
• No makeup exams will be given unless official justification is shown! So, be sure to show up for the midterm on July 31(Weds), 2002. Absence from the midterm will automatically lead to "fail" in the final grade.
  
• HW1 is complete. It's due on July 29(Mon), 2002.
  
• Midterm is coming up! It's in class on July 31(Weds), 2002. It covers Sec 4.4, 11.1, 11.2, 11.3, 11.4, 11.5, 11.6 and 11.7. This is a lot! So, start preparing early. Tuesday might be too late. The best way to prepare is to review hw assignments and your lecture notes. If you are concerned about your speed, practice more on similar problems from the textbook.
  

Textbook

James Stewart, Calculus: Early Transcendentals, Fourth Edition

We'll mainly cover chapter 11. Part of chapter 4 will be added.

Prerequisite knowledge

21-115 and 21-116 (or equivalents).

Hours

Lecture hours: (MTWRF) 10:30AM-11:50AM PH A20
Office hours: Mainly by appointment (pyu@andrew.cmu.edu) at WEH 6403

Grade

There will be weekly homework assignments, a midterm and a final. Each of the midterm and the final will be given in class for 1 hour and 20 minutes. For the overall score, HW takes 20%, midterm takes 40% and final takes 40%. The final is NOT comprehensive, focusing only on the material covered after midterm. (Notice the material is accumulative, so there's no way to avoid stuff done in the early stage of the course completely while testing the later stuff.) The final grade is determined according to the following scale:

• A: 90-100
  
• B: 80-89
  
• C: 70-79
  
• D: 60-69
  
• Fail: 0-59
