Miscellaneous Resources
- It will be important for you to read your textbook in this course.
If you are unfamiliar with reading mathematics textbooks, here is a
collection of Tips for Reading Your
Mathematics Textbook that I have written.
- An online
matrix calculator that you can use to check some of your matrix
calculations.
- The history of mathematics is an important subject. It gives a
context in which to view the results that one learns in math classes.
Furthermore it shows that mathematics is, first and foremost, a human
activity. In the historical development of Linear Algebra, we see that
the concept of a vector dates back as early as the work of Bolzano in the
beginning of the 19th century. Initially vectors were used in the study
of geometry, giving a way to "coordinatize" space. Transformations on
space often took the form of matrices, and this prompted the study of such
matrix properties as determinants and canonical forms. Later, in the work
of Poncelet and Chasles, a move was made to a coordinate-free, or
synthetic, geometry. This was the beginning of the notion of an abstract
vector space, in which one replaces concrete spaces by abstract spaces
satisfying certain axioms, and in which matrices are replaced by linear
operators on these spaces. Today the influence of Linear Algebra
extends far beyond geometry, and the concept of an (abstract) vector space
arises in a variety of contexts. Consequently, Linear Algebra has had
applications to numerous areas of mathematics as well as many areas of
physics.
