General Expectations
The Department of Mathematics has a general expectations statement, which we are assumed to follow in this class.
Reading
In this class we use the book
  • Bernard Kolman, David R. Hill; Elementary linear algebra with applications, ninth edition Pearson Prentice Hall.
    The book is really unavoidable, and cannot be replaced with another textbook! There are, however, many linear algebra textbooks which may be useful. Linear Algebra by K. Hoffman and R. Kunze, Prentice Hall, is of particular interest. It covers much more material than this class.
    Course Objective
    To learn first basic ideas and notions of linear algebra. It is particularly important to learn to operate with these ideas and notions. This includes both the ability to conduct a specific calculation, and to prove or disprove a statement. Since this is a writing intensive class, to produce a mathematically rigorous argument (aka a proof) means to write it down in proper English.
    Prerequisites
    Calculus III (i.e. 243 or 253A), or concurrent.


    Grading Policy
    The course contains a combination of concepts, ideas and techniques, which the students must be able to apply in solving specific problems. Some of these problems require to either prove or disprove a certain statement. At the end of the day, your grade will reflect your ability to solve specific problems and to properly write your solutions down. This assumes your ability to read and understand the textbook. To understand, in this context means to be able to both create mathematical arguments (proofs) which are similar to those provided in the text, and to perform specific calculations similar to those in the exercises and examples. More specifically, the following rules are to be taken.



  • Final exam will count for 30% of the final grade. The exam is cumulative (it covers all the material). The exam will take place on Tuesday, December 14, 9:45 - 11:45am.

  • Four Writing Homework Assignments count together for 40% of the final grade.
  • Three Quizzes will be given, and the average grade for the quizzes counts for 30% of the final grade.
