Math 314 Matrix Theory Home Page Spring, 1999 Mark Brittenham

This page is devoted to materials and links specific to Mark Brittenham's Math 314 class for Spring, 1999. Here you may find lists of homework assignments, dates for exams, as well as lists of topics covered by these exams, an html-ized copy of the course summary, and anything else that might come up.

Some linear algebra links: A general page of links to linear algebra resources includes a set of WebNotes by a former UNL professor, which in turn points to a web-based Maple V front-end. (The only problem with the front-end is that it has no help file, so you need to memorize the appropriate commands in order to use it.) As an example, you can cut and paste this stuff in:

with(linalg);
A:=matrix([[.1,.3,.7],[.4,.3,.1],[.5,.4,.2]]);
v:=matrix(3,1,[.2,.3,.5]);
w:=matrix(3,1,[.9,0,.1]);
evalm(A^20*v);
evalm(A^20*w);

(These are examples of Markov chains. If you want to have some fun, change the 20's to 20000's.... note the amount of time (at the bottom) each takes...)

Some (mathematical) links that might be of general interest:

A site called SOS Math at the Univ. of Texas at El Paso offers pages of material on topics ranging from polynomial long division, the quadratic formula, and trigonometric identities, to Taylor polynomials, the Cauchy-Riemann equations, and Matrix algebra.
Another site covering similar material, including solved homework problems for you to practice on, is kept in Belgium.

Dan Sloughter has a web page containing Java programs for visualizing various mathematical concepts. My favorite is one which will draw the Taylor polynomial approximations for y=sin(x) .

A site called Karl's Calculus Tutor currently covers most of what would qualify as first-semester calculus, and some of the second semester, as well.

Forget a geometry formula? Check this page at Trinity College.

A Java-enabled page for generating Pascal's triangle (or rather, the last two digits of each entry, which is good enough through the 24th line). What's the pattern of the even numbers in the triangle?!
