Linear Algebra and Its Applications

Course Description
Linear Algebra deals with systems of linear equations, their fundamental
properties, and transformations of vector spaces. The basic objects of
the course are vectors and matrices.
Linear algebra techniques are widely used in many areas, such as mathematics,
engineering, economics, finance. They are also cornerstones for a variety
of advance classes in science and engineering. The course will describe
basic basic concepts and tools of linear algebra.
We will try to cover the following material:
Sections
1.1-1.9,
2.1-2.3,
3.1-3.2,
4.1-4.6,
5.2-5.3,
6.1-6.4.
We may cover these topics in a different order.
Depending on time we may cover more (or delete) topics.
Course Objectives
The following three topics will be emphasized:
-
the algebra of linear equations and matrices,
-
the geometry of vector spaces,
-
algorithms for solving linear equations.
By the end of the class one should know:
-
to characterize existence, uniqueness and solution sets of systems
of linear equations via the row reduction algorithm,
-
to perform matrix operations, including inverse and determinant
computations,
-
to characterize vector spaces or subspaces, and determine their dimension
and matrix ranks,
-
to compute eigenvectors and eigenvalues, and perform matrix diagonalization,
-
concepts of orthogonality and orthogonal bases, carry out
orthogonal transformations and projections.
Homework, Quizzes, Tests, and Grading
Homework
-
Weekly homework will be assigned on Thursday and collected the following
Thursday.
-
The two lowest homework grades will be disregarded.
-
Please staple your homework, and present the problems in the order
assigned, if you want credit.
-
No late homework will be accepted.
Quizzes, Tests, and Grading
The final grade will be based on homework grades (20 pt),
four quizzes (20 pt each), and the comprehensive final (50 pt).
