This program will graph functions of the form y = f(x), functions of the
form x = g(y), polar equations of the form r = r(t), where t is the angle,
as well as parametric equations of the form x = x(t), y = y(t).  Up to nine
equations can be plotted.  It also computes line integrals over these curves.
   When you have finished reading this document, you will be presented with a
choice of options.  You can use the right-arrow and left-arrow keys to
highlight your choice.  These keys are on the right hand side of the
keyboard. When your choice is highlighted, select it by pressing the RETURN
or ENTER key.
   You can always get HELP by pressing the F1 key, usually located on the
left hand side of the keyboard.  When you have finished with help, press the
ESCape key.  Why not get HELP now, by pressing F1?
   The first thing you should do, after you finish reading through this, is
create the functions you want to work with.  This is done through the
FUNCTION OPERATIONS option.  After you have created a function, you can plot
it by selecting GRAPH FUNCTION.
   You can always re-read these instructions later by going to the OTHER menu
and selecting INSTRUCTIONS.
                       Press the ESCape key, when finished.
