            Using and installing the program Vector

Purpose of the Program:
     Trigonometry and vectors can be difficult subjects because of
the innate fear many students have of mathematics.  This program
is designed to help the student in the understanding of both
trigonometry  and vectors in a non-threatening manner which is
conducive to understanding.  A lab which can be used with the
program is included with the registered copy.

Installing Vector on your hard drive:
     To install vector on your hard drive type start windows and
click on File in the upper left hand corner of Program Manager.
Choose Run from the file menu and type and enter path\install where
path is the location of the vector files.  If using Windows 95
click on Start in the lower left hand corner, click on Run and then
enter path:\install.   For example, if the files are on the root
directory of A drive you would enter A:\install. Install will
create a directory called C:\VECTOR, copy all of the appropriate
files, and create the necessary icons.

Using the Program:
     Click on the icon to start Vector and select Trigonometry (or
press F2).   The user will be presented with a right triangle.  The
triangle will contain either two sides or a side and an angle. 
Using trigonometry the user is to determine the remaining sides and
angles of the triangle.  The dialog box will contain the known
values.  Enter the calculated values into the dialog box and click
on OK when completed.  To move around the dialog box either use the
mouse or TAB key.  The user will be informed of correct and
incorrect responses.

     To use the vector part of the program click on either the Two
Perpendicular Vectors choice (or press F3), the Two Non-
erpendiuclar vectors choice (or press F4), the Two to Five 
vectors choice(F5), or Resolve a single vector(or press F6).  
For the first 3 choices the user will be presented with vectors 
which are to be added together.  Click the left mouse button on 
any vector and drag the vector so that  it is added head to tail 
with any other vector.  If the procedure is done correctly the 
vector will be placed on a graph with the correct directions 
indicated.   When adding large numbers of vectors the 
resultant vector may go off screen because of space
limitations.  
     A dialog box will appear asking for the magnitude and
direction of the resultant vector.  Using trigonometry, the law of
cosines, or vector component addition the user is to determine
the magnitude and direction of the resultant vector.  Enter each
in the dialog box.  To move from entry to entry use the mouse or
TAB key.
     When resolving a single vector(F6) enter the magnitude
of the vertical and horizontal components of the vector into
the dialog. box.

Angle Mode Menu:
     The default angle arrangement for the vector portion of the
program is the traditional coordinate system where 0 degrees is to
the right, 90 degrees is up, 180 degrees is left, and 270 degrees
is down.  To switch to the Compass system where 0 degrees is up
(North), 90 degrees is right (East), 180 degrees is down (South),
and 270 degrees is left (West) click on Compass.

Exiting the program:
     To quit the program select this menu item or press Alt-x.

Help can be obtained at any time by clicking on the Help Menu item.
