PROJECT Due April 26

About the course: This is a first undergraduate course in linear algebra. In this course you will learn many of the foundations of linear algebra. Students are encouraged to use Maple to complement the topics, in fact this practice will be very useful for the future development of the projects. We will present several applications to motivate the subject. Two Maple Projects will be assigned during the semester.

In this course you will learn about: vectors, matrices, linear systems, dimension, rank and linear transformations. You will be computing determinants, eigenvalues and eigenvectors and will learn and use the concept of orthogonality.

Time permitting you will learn about vector spaces.
