**PRQ:** MATH 232, Calculus III

**TEXT:**
Bernard Kolman and David R.Hill,
**Elementary Linear Algebra**, *9th Edition,*
Prentice Hall, Upper Saddle River, New Jersey, 2008.

**SYLLABUS:**
The course will cover most of Chapters 1-7 of the text.

**COURSE OBJECTIVES:**
Students will develop computational skills
in working with linear transformations
and the matrices used to represent them.
However, more of the course will focus on non-computational issues
such as reasoning and constructing proofs.
This course is intended as a transition
between the beginning calculus courses
and upper level courses in mathematics.

**CALCULATORS:**
This course is not focused on numerical computation.
Students may wish to use calculators or computers as a study aid,
but no electronic devices of any kind will be allowed on exams.
See
this
page for some examples that illustrate the difficulties
in doing numerical calculations.
*A calculator can give you a completely wrong answer.*
Techniques from numerical linear algebra
are covered in a subsequent course, MATH 434.

**GRADING:**Grades will be based on exams, quizzes, and homework. There will be

**3 hour exams worth 100 points each****Homework and/or Quizzes, approximately 100 points total (may vary by section)****Final exam, 200 points**

**FINAL EXAM:**
The final exam will be a comprehensive, departmental examination.
It is scheduled as a mass exam, on
**Thursday, May 11, 8-9:50AM.**
All sections of this course will take the same final exam at the same time.

**WITHDRAWAL:**
The last day for undergraduates to withdraw from a full-session course is
**Friday, March 10.**

**LECTURES AND EXAMS:**
This is the tentative schedule for lectures and exams.

**ACADEMIC CONDUCT:**
Academic honesty and mutual respect (student with student and instructor
with student) are expected in this course. Mutual respect means being on
time for class and not leaving early, being prepared to give full
attention to class work, not reading newspapers or other material in
class, not using cell phones or pagers during class time, and not
looking at another student's work during exams. Academic misconduct, as
defined by the Student Judicial Code, will not be treated lightly.

**DRC STATEMENT:**
If you have specific physical, psychiatric, or learning disabilities and
require accommodations, please let your instructor know early in the
semester so that your learning needs may be appropriately met. You will
need to provide documentation of your disability to the DRC (Disability
Resource Center) Office located in the Health Services Building, 4th
floor.
