Teaching Assistant: Haoyuan Liu
Text: Differential Equations and Linear Algebra (2nd Ed.) by Stephen W. Goode
Homework will be given approximately weekly. On each
assignment a few selected problems will be graded. It is OK to
help each other solve homework problems, but it's not OK to turn in
essentially identical solutions--once you have discussed homework
problems so that you understand better what to do, you should write the
solutions on your own. Homework will be accepted up to 2
lectures late, with a 20% penalty. Not accepted more than 2
Quizzes: There will be two or three quizzes during the term, in discussion session, typically the week before the exam. (Exact dates to be announced in lecture.)
Exams: Two midterms plus final. Tentative midterm
dates are Friday February 17 and Wednesday March 29. Final is
Monday May 8, 8:00-10:00 am. The final is cumulative but with
greater emphasis on material after the second midterm.
exam information: The final will be held Monday May 8,
8:00 - 10:00 a.m., in the lecture room (SOS B46). Closed book, no
calculator, but you are allowed one 8 1/2 x 11 sheet (2 sides) of
handwritten notes. An optional review
session with Haoyuan will be held Saturday May 6, 11 a.m. - 3
p.m. in VKC 101. An optional SI
review session with Nitin will be held Monday May 1, 5 p.m. - 8
p.m. in GFS 106.
Missed exams: There will be no makeup exams. In exceptional cases, with a written excuse, if you miss an exam I will base your grade on the exams you did take.
Grading: Homework + quizzes 25%, midterms 20% each, final 35%. No fixed quotas of A’s, B’s etc. The number of points needed for a particular grade is not fixed in advance--if the exam turns out to be difficult and scores are low, then fewer points are needed for an A, for a B, etc.
Auditing: If you want to just sit in on the class, you must register for an audit.
Material to be covered: Parts of Chapter 1; most of Chapters 3-8. The following schedule is approximate:
3.1 - 3.7 9 lectures
4.4, 4.3 3 lectures
5.1 - 5.7 7 lectures
6.1, 6.3 - 6.7 6 lectures
1.2, 1.6 2 lectures
7.1 - 7.4 5 lectures
8.1 - 8.7 7 lectures
Midterms 2 lectures
Extra time for topics requiring it: 2 lectures
Everything in this syllabus is in principle tentative; if necessary
it will be adjusted during the semester.
Additional help: There are TA's in the Math Center Mon. - Fri., 8 am - 6 pm. Most of them can help you with Math 225. Also, help is available through Supplemental Instruction (SI)--details later. The SI leader for this lecture is Nitin Sharma. More information about SI is here. Nitin's sessions (which are completely optional) are held as follows:
