MATHEMATICS - UNIVERSITY OF TEXAS http://www.math.utep.edu/sosmath/home.html The website of the Department of Mathematical Sciences at The University of Texas at El Paso offers resources to help students do homework, prepare for a test, or get ready for class. Others might like to use its pages to practice their math skills. The material presented reviews the most important results, techniques and formulas in college and pre-college mathematics. The learning units are presented in worksheet format and require students' active participation. Extensive reviews cover Algebra, Trigonometry, Calculus, Differential Equations, Complex Variables, and Matrices.

This first group of Web pages presents symmetries called isometries, which preserve distances. The unit defines various transformations and isometries and offers exercises that make use of the Geometer's Sketchpad and KaleidoTile. The wallpaper unit studies plane patterns whose symmetries are translations, glide reflections, and rotations. Students learn to use Kali, a computer program that generates plane patterns. Supplemental materials include "Names for features of symmetrical patterns" from GEOMETRY AND THE IMAGINATION, a two-week summer workshop led by John Conway, Peter Doyle, Jane Gilman, and Bill Thurston at the Geometry Center in Minneapolis, Minnesota in June 1991. http://www.geom.umn.edu/docs/education/institute91/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THIS IS MATH AWARENESS WEEK! 20-26 April 1997 http://mathforum.org/maw/ The 1997 theme of Math Awareness Week is MATHEMATICS AND THE INTERNET. Mathematics is the language of Internet operation, from the binary numbers that describe text and images to the complex data structures of search engines for the World Wide Web. Ideas from fields like number theory have led to such key Internet technologies as data encryption for secure financial transactions and data compression for audio and video. At the same time, the Internet has given birth to world-wide collaborations among mathematics teachers and researchers, collaborations that are advancing both kindergarten through undergraduate education and our understanding of some of the most difficult problems in pure and applied mathematics. Institutions across America and beyond are celebrating Math Awareness Week (MAW) right now! All this week, invited lecturers will speak, posters will receive awards, math call-in radio shows will be on the air, and students everywhere will gain a better appreciation of math.
