Systems of linear equations; matrix algebra, inverses, determinants, eigenvalues and eigenvectors, diagonalization; vector spaces, basis, dimension, rank and nullity; inner product spaces, orthonormal bases; quadratic forms.
This course has a twofold aim: (1) develop proficiency in the concepts listed above, and (2) transition students into abstract mathematics thorugh development of good habits of understanding, communicating, and writing proofbased mathematics.
Required for AM majors, elective for other majors.



MATH 251, multivariable calculus. In particular, some awareness of algebraic and geometric properties of vectors in 2 and 3space.


Textbook

Elementary Linear Algebra by Howard Anton, 10th ed., John Wiley and Sons



 Students will learn how to solve systems of equations through various techniques,
especially through row reduction of matrices.
 Students will learn properties of matrices, especially invertibility, and matrix
algebra.
 Students will learn general vector spaces and linear transformations. The primary
vector spaces studied are Euclidean, matrix and polynomial spaces. Topics
include linear independence, column and row spaces, nullspace, basis and
dimension (including rank and nullity).
 Students will explore eigenvectors and eigenvalues and learn how to diagonalize a
matrix.
 Students will learn about inner product spaces and orthogonailty. Topics include
orthonormal bases, the GramSchmidt process, best approximation, and their
applications to QRdecomposition and least squaresfitting.
 Students will learn about applications of linear systems in sciences and
engineering.

Reasonable accommodations will be made for students with documented disabilities. In order to receive
accommodations, students must obtain a letter of accommodation from the Center for Disability Resources
and make an appointment to speak with me [the instructor] as soon as possible. The Center for Disability
Resources (CDR) is located in Life Sciences Room 218, telephone 3125675744 or disabilities@iit.edu.
