    To understand the natural numbers, wemust first understand the primes. Yet the be-havior of the primes remains for the most parta mystery. For example, despite the efforts of many great mathematicians over hundreds of ...
  • O’Maley, Amiee (2005)
    Quadratic equationsare studied extensively within mathematics throughout astudent’s high school and college careers. The standard form for these equations(in the variablex) is given by
  • Malone, William (2005)
    The notion of a negatively curved group is at first highly non-intuitive because it links two areas of mathematics that are not usually associated with one another. Curvature is generally a property that we associate with ...

  • Malone, William (2004)
    How would you go about finding, say, the billionth digit of π? There are many algorithms, that can calculate the billionth digit of π in various bases within a reasonable amount of time on a powerful computer system. ...
  • Casey, Jeff (2004)
    Options or “privileges” as they were known in early 19th Century America actually appeared on the financial scene around the same times as stocks. Ini- tially, there were numerous problems with the trading of options. The ...

    The first cwatset was discovered in 1987 by Erich Friedman, then a student at Rose-Hulman Institute of Technology. Cwatsets were originally developed for statistical purposes, as a means of creating typical subsamples from ...
  • Christian, Nicholas; Johnson, Mathew (2004)
    The ability to determine whether there are any defects in the interior of an object without destroying it is an invaluable tool in today’s industries. One popular method for doing this is steady state thermal imaging. This ...
  • Brown, Timothy (2004)
    In the typical elementary classroom, students are expected to learn and master their addition facts through countless practice problems and rote memoriza- tion. Yet for many teachers, the biggest mathematical frustration ...
  • Smith, James (2004)
    There are many phenomena in the world that, upon close observation, are clearly related. For example, when profits decline, unemployment rises. When weather conditions worsen, drivers have more accidents. The goal of an ...

  • Savic, Milos (2004)
    A function, or a signal as electrical engineers like to call it, can be decomposed as a sum, possibly infinite, of sines and cosines, called its Fourier series expan- sion. The coefficients in this decomposition represent ...
  • Londino, Gina; Waung, Connie (2004)
    Our project focus was to determine the proportion of students who have cheated on a test at least once in the past year. Out of the students that cheated we were then to determine if a student was more likely to be a ...
