* DocWriter (C) 1996 by Paul A. Houle (ph18@cornell.edu)
*
* DocWriter, like many good things in life, is free. You can find out
* more about DocWriter at
*
* http://www.msc.cornell.edu/~houle/javascript/DocWriter.html
*
* DocWriter uses LiveConnect to output a table of sines, cosines, and
* tangents to another browser window. The user can then print the results
* or save them to a file. LiveConnect is only available on Netscape 3.0
* as of the time of this writing.
