Textbook Numerical Mathematics and Computing fifth
edition, by W. Cheney and D. Kincaid. Available from Pitt Bookstore.
This course is an introduction to numerical linear algebra which addresses numerical methods
for solving linear algebraic systems and matrix eigenvalue problems
and applications to partial differential equations.
Although the course will stress a computational viewpoint,
analysis of the convergences and stability of the algorithms will be investigated.
We will cover the following chapters in the textbook: systems of linear equations, ordinary differential
equations, least-squares method, boundary value problem, partial differential equations
and minimization of functions.
This course fulfills the
for the following Math majors:
The Bachelor of Science in Mathematics,
The Bachelor of Science in Applied Mathematics,
The Bachelor of Science in Actuarial Mathematics,
The Bachelor of Science in Mathematical Biology,
offered by the
Department of Mathematics.
Grading Policy The final grade will be based on
homeworks (40%), and exams (60%).
Late homework will be accepted only by special permission of the

Disability Resource Services
If you have a disability for which you are or may be requesting an
accommodation, you are encouraged to contact both your instructor and
Disability Resources and Services, 140 William Pitt Union,
412-648-7890 or 412-383-7355 (TTY) as early as possible in the term. DRS will verify your disability and determine reasonable accommodations for this course.
Cheating/plagiarism will not be tolerated.
Students suspected of violating the University of Pittsburgh Policy on
Academic Integrity will incur a minimum sanction of a zero score for the quiz,
exam or paper in question. Additional sanctions may be imposed,
depending on the severity of the infraction.
On homework, you may work with other students or use library resources,
but each student must write up his or her solutions independently.
Copying solutions from other students will be considered cheating, and handled
Statement on Classroom Recording
To address the issue of students recording a lecture or class session, the University's
Senate Educational Policy Committee issued the recommended statement on May 4, 2010.
"To ensure the free and open discussion of ideas, students may not record classroom lectures, discussion and/or activities
without the advance written permission of the instructor, and any such recording properly approved in advance can be used
solely for the student's own private use."
