Math 217: Linear Algebra Section 5

Professor Karen E. Smith
East Hall 3074

Section 5 meets Winter Semester 2016
MWF 11:40 am--1 pm in East Hall B743 (in the basement)

Important Info and Detailed Syllabus.

This is the webpage for Section 5 only. There is also a MATH 217 COURSE WEBSITE used by all sections through Canvas. You will need to check both these places for info and to download information.

Math 217 is a first course in linear algebra with proofs. Here is a Detailed Syllabus, the same for all sections. In addition to learning linear algebra, a main goal of the course is to teach students how to make a rigorous mathematical argument.

Math 217 is a NON-LECTURE course. This means students are responsible for learning the material on their own through individual reading of the textbook working through more theoretical concepts in small groups using worksheets in class, working through more computational exercises using online webwork, and completing two-part written problem sets every week (due Fridays).

Most students find this a very challenging course, especially those who have never done "proofs" before. In order to succeed, it is crucial to do all reading both before class, and again after to ensure full understanding, complete webwork as soon as possible as it is assigned, start early on weekly problem sets, and get help from me or any other 217 instructor as soon as you need it.

In addition, you can get help in the Math Lab whenever it is open.

All sections of Math 217 follow the same syllabus, take the same midterm and final exams, have the same online-webwork and weekly written assignments, and have the same grading scheme. There are, however, some minor differences between sections. In ours, for example, ATTENDENCE IS REQUIRED and Quizzes will be frequent. Also, Section 5 students are expected to check the Daily Update every day, which will usually let you know when a quiz is coming and the reading assignment. No make up quizzes will be given (barring extreme situations--talk to me); however, your lowest two scores will be dropped.

TESTING AND DISABILITY: If you think you need an accommodation for a disability, please let me know as soon as possible. In particular, a Verified Individualized Services and Accommo dations (VISA) form must be provided to me at least two weeks prior to the need for a test/quiz accommodation. The Services for Students with Disabilities (SSD) Office (G664 Haven Hall; ) issues V ISA forms.
