Visual Trigonometry is a fully functional, interactive Windows program that visually demonstrates the functions and theory of trigonometry.  Requires VBRUN300.DLL (free from Compuserve) in your WINDOWS\SYSTEM directory.  To register, GO:SWREG.

If you do not already have VBRUN300.DLL in your WINDOWS\SYSTEM directory, you can download it from many of Compuserve's forums, including MS Windows Software Library (GO:MSL) as filename VBRUN300.EXE and MS Windows Shareware Forum (GO:WINSHARE) as filename VBRUN3.ZIP.

This copy of Visual Trigonometry is fully functional and has all the features of the registered version; however, you may only use it three times, without registering, before it becomes inactive.  There is no limit on the length of time that it can be used each time.

To register Visual Trigonometry, GO:SWREG, the Compuserve Shareware Registration forum.  Search by the filename that appeared in the forum from which you downloaded the file, by the program name (Visual Trigonometry) or by the author's ID (72152,567).  In any case be sure that the author's ID (72152,567) matches.  If you search by author ID you may find other applications that also may be of interest to you.  The (very reasonable) price will be added to your Compuserve account.

Running Visual Trigonometry is easy.  Just double-click the .EXE file in you File Manager or add the program to a group using Program Manager ("File," "New ...").  Once you are running, click on the "Guide" ICON for further instructions.  You'll find that the program is simple to use and that most functions are intuitive.

Enjoy Visual Trigonometry!  Any feedback would be welcomed (Address to ID 72152,567).
