IMBROGLIO QUADRATIQUE 2.0 HELP DOCUMENT
---------------------------------------

HOW IT WORKS:
-------------
Quadratique uses the quadratic equation formula to solve equations:

	x = -b  sqrt(b-4ac)
	    -----------------
	           2a

Quadratique uses numerous subroutines and functions which simplify
fractions, perform common operations on fractions, work with imaginary
numbers, and format numbers.

FEATURES:
---------
Quadratique was specifically designed for the student in mind, though it
can be used by anybody. Its interface is easy to use and understand. All
answers are given in a simplified (fractional/radical) format when possible,
as well as the decimal format. It also allows the user to obtain important
information about Quadratic functions.

- the coefficients may be entered in...
	... decimal format (e.g. 123.4567890)
	... fractional format (e.g. 321/654 or 12.345/678.9)
            * note that the backslash must face forward ('/'), and there
              may be no empty spaces in the fraction
	... exponential form (e.g. 0.234E5 or 4567.890E-10)

- to save time...
	... when there is no coefficient entered into a text box before
	    an 'x' term , the coefficient automatically becomes '1'
        ... when no constant is entered, it automatically becomes '0'
        ... when only a negative sign ('-') appears in a coefficient
            text box preceding an 'x', the coefficient automatically
	    becomes '-1'

- the program displays error messages when it encounters problems,
  notifying the user of what could have gone wrong, as well as possible
  solutions

- the nature of the roots is displayed at the bottom of the window

- roots are displayed in decimal format, and, if different, a radical+
  fractional format (displaying the root in fractional and/or radical
  terms)

- the sum and product of the roots are displayed in decimal and/or
  fractional format
	    
- the full equation and its roots can be copied to the clipboard using the
  'Copy' command, to be pasted later into other applications

- all coefficients and solutions can be quickly cleared using the 'Clear'
  command

- after solving an equation, in order to edit the coefficients and solve
  again, hit the 'Edit' button

- Quadratique is also equipped to solve linear equations...
	... to do so, enter a coefficient of '0' in the 'x' term in order
	    to enter a linear equation

- after solving a quadratic equation, information about the corresponding
  quadratic function can be viewed by clicking 'Function' (the information
  will be displayed in fractional format, with the exception of the
  abscises, when possible)
  * if the original equation was ax+bx+c=0, then the corresponding
    function would be y=ax+bx+c

- after solving a linear equation, information about the corresponding
  linear function can be viewed by clicking 'Function'

- the information on the functions can be copied to the clipboard by hitting
  'Copy' from the Functions window

BUGS:
-----
- During internal calculations, very small numbers are sometimes interpreted
  as being equal to zero, and are changed to zero. As well, the computer
  accuracy is quite limited. Combined, these may sometimes cause very slight
  errors in the calculations, and thus affect the solutions. It is important
  to note that even the tiniest of accuracy errors may be multiplied many times
  during the calculations.

- The equation solver cannot handle excessively large input, and will
  usually generate an error message.

- Sometimes Quadratique will not recognize that a number is a perfect square,
  and in the simplified roots text box it will display sqrt(n) instead of
  'n'.
