2 Course Goals
The
course is an introduction to the study of simultaneous linear equations in
several variables. For example, the description of the tangent space to
an n-dimensional surface sitting in n + r - dimensional Euclidean space
is recognized as an n-dimensional vector subspace. A handy overview is
presented in Linear algebra-Wikipedia.
Recall that in Calculus 3 one started with the coordinatization of three dimensional space via Cartesian coordinates; then began the algebraization of geometry with the introduction of vectors - directed line segments. Geometric operations on line segments were interpreted as algebraic operations on vectors to give an algebra for vectors in both the plane and three dimensional spaces. Not only does this include addition and multiplication by scalar quantities, it also provides two different types of multiplication - the dot and cross products. These products are geometrically defined and Calculus 3 spent some time applying vector algebra to the geometry of three dimensions. Now we begin a more unified theory which allows us to go to dimensions higher than 3.You shall see how matrix algebra is used to calculate with functions of more than one variable - a version of higher order arithmetic. For example, the derivative of a function from the plane to 3-space is properly regarded as a linear transformation which can be represented by a 3 by 2 matrix. Matrices can be added, subtracted, multiplied by scalars; compatible matrices may also be multiplied and so there is an algebra of matrices.

Your
grade for the course will be based on two exams during the semester, a
final exam, weekly homework and quizzes. Each of the four components will
count toward your grade. The term exams will count 100 pts each and the
final 130 pts. HW and Quizzes count 100 pts.each. The final exam is at 10:30 am in CB 347. on Thursday, May 5, 2016.
5 Quizzes: (100 points) There will be weekly in- class quiz problems. I will give a selection of these problems prior to the time of the quiz.Your course score will be the sum of your test, homework, and quiz scores.
6 Attendance Policy:
Grading for the course will be influenced by class attendance. You
will
be allowed 4 unexcused absences; for every missed class after that you
will lose 5 points on your final grade (that is half a letter grade).
Roll will begin anon.
Students
are expected to attend each class meeting unless he or she has been excused by
the instructor. Failure
to attend class will result in a lower grade, and may result in failing the
class. Absences due to illness
or emergencies must be reported within a week. You may call the instructor’s office
or email him at the
numbers/address listed on the first page of this syllabus. When there is an
excused absence, students
will be given the opportunity to make up missed work and/or exams.
The
following are typically accepted reasons for excused absences:
1. Serious
illness.
2. Illness
or death of a family member.
3. Approved
University-related trips.
4. Major
religious holidays.
5. Other
circumstances found to be "reasonable cause for nonattendance.”
It is important to take each exam on schedule. Missed work may be made up only due to illness with medical documentation or for other unusual (documented) circumstances. Students who have university excused absences or who have university-scheduled class conflicts with uniform examinations may arrange with their instructor to take the exam at an alternate time. Work-related conflicts are neither university excused absences or university-scheduled absences. If you miss an exam, you receive a zero. You will be eligible for a make-up only if you present a valid excuse to me before the exam. If you cannot find a reasonable arrangement for a make-up, contact the department DUS Serge Ochanine. Students anticipating an absence for a major religious holiday are responsible for notifying the instructor in writing of anticipated absences due to their observance of such holidays no later than the last day for
adding a class. Information regarding dates of major religious
holidays may be obtained through the the religious
liaison.
