Readme File for the Plotter - Release 1.0
*****************************************

With this MS-Windows-based plotter you can:

- Input ANY standard function using traditional syntax
and PLOT THE GRAPH of that function on a given interval, [a,b].

- EVALUATE THE FUNCTION at any given point in its domain

- FIND ITS ROOTS (to the right of a given point) so that
you can check your calculations using Newton's method for
finding the roots

- FIND THE EXTREMA (critical points) to help in sketching
the graph of the function on your own.

This program should be used in order to complement your
course notes rather than replace them.

Installation:
_____________

***********Windows 95 or Windows NT 4.0**************

- Double Click My Computer
- Double Click the letter of your floppy drive e.g., a:\
  [ A window showing your a:\ contents will appear...]
- Double click the application entitled "Pr6" 
- The application is launched from the floppy onto your
  desktop and you can use it right away.

***************Windows 3.1 or 3.1.1:*********************

- Go the Program Manager
- Under the menu item "File" select the item "Run"
- Type in the command "a:\pr6" (or whatever other letter your
  3.5in floppy drive may be)
- The application is launched from the floppy onto your
  desktop and you can use it right away.


******************IMPORTANT NOTES************************

1. The natural logarithm function is denoted by the universal 

log(x)

instead of the usual " ln(x) ". The log with base 10 of 
x is denoted by log10(x), so that log10(10)=1.


2. The nth root function is denoted by the conventional

rootn(x) 

where n is a POSITIVE INTEGER (so that the quantity
root3(-8) returns an ERROR). For example, the
cube root of x is denoted by 

root3(x)

so that root3(8) = 2. 


*************Examples of acceptable syntax for input********

powers and sum and differences...

3*x^3 -2*x^2 + x^(1/3)

represents the function "Three (times) x cubed minus 2 (times)
x squared pplus x raised to the power 1/3 "

Absolute value, trig. functions, inverse trig functions ...

abs(x - x^3) + Arctan(sin(x)) - (sin(x))^2

represents the function "The absolute value of the function x
minus x cubed plus the arctangent of the function sin(x) 
minus the sine of x (all) squared".

The inverse functions arccosecant "Arccsc" and "Arcsec" may
be defined in terms of the elementary functions given in
the Help menu of the program.[See the author's "ABC's of Calculus:
Module on Inverse Functions", The Nolan Company, Ottawa, 
1994, for more information on inverse functions].
