Visualizing Infinite Series - Lanius | NASA Spacelink |
Dictionary of Units of Measurement VISUALIZING AN INFINITE SERIES - Cynthia Lanius http://math.rice.edu/~lanius/Lessons/Series/infinite.htm This lesson uses a trapezoid successively divided in fourths as a visual representation of an infinite geometric series, a mathematical concept that is often only treated symbolically. Explorations are outlined for investigating a number of series, and links to related sites are provided. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- NASA SPACELINK http://spacelink.msfc.nasa.gov/.index.html An aeronautics and space resource for educators.
