General Information for my section:
 Lecture class meetings are Mondays, Wednesdays and Fridays

 Section 214; Thursdays 9:3010:30 am in DRL 4C4
Recitations begin on Wednesday, January 10 (which is a University Monday)
 The text book is Differential Equations and Linear Algebra
by Goode and Annin, 4th edition.
 The
Syllabus and Core Problems on the Math Department's Math 240 site.
 Old final exams and other useful information
(including the syllabus) can be found on the
the Math Department Math 240 page.
 The exams will generally be set at the level of the Core Problems.
The old final exams are regarded as part of the Core Problems.
 Remarks about the old final exams
 There was a major change of the syllabus of math 240 in fall 2012.
You will find plenty of problems involving line integrals, surface integrals,
Stokes theorem and divergence theorem in the exams before that. You can
safely ignore those questions in old exams, but questions about linear
algebra and differential equations in the "older final exams" are still
quite relevant.
 Each assignment contains problems from old final exams.
Basic Ground Rules:
 The COURSE GRADE is based on:
Homework (10%), Midterm exams (45%)
Final exam (35%), Quizzes and everything else (10%)

Homework will be assigned the weekend before, and will
be due at the beginning of Friday's lecture the following week.
 Homeworks will be spot graded and returned in the recitations.
Answers to selected problems will be posted on the web by
late Friday or early Saturday.
 LATE WORK will NEVER be accepted.
 You can hand in your homeworks early, either in person or
by other arrangement.
Never leave your homeworks in any mail box of the mathematics
department.
 Homework will contain instructions for reading.
Make sure you do the reading before the class for which
it is assigned. I will assume you have done so.
 You are responsible for doing all the core problems, including the
old exam problems. They form a constant part of your home
work assignment.
 You are encouraged to work in groups and discuss with each other.
But the work you hand in MUST BE YOUR OWN WRITEUP. See
Penn's code of academic integrity.
 You can use a handwritten note sheet (both sides) at most
8.5'' by 11'' in size during the inclass midterm
and final exams. No electronic device is allowed. (We will make an
exception for "dumb" watches.)
All electronic devices, including cell phones and smart watches,
should be put in your bags with ringers off during the entire exam.
Note that you cannot use a cell phone as a timepiece.
Using any communication device (including computers, cell phones,
calculators, PDA's, smart watches, etc.) during these exams is a serious breach of
academic integrity.
