IMBROGLIO QUARTIQUE 1.0 HELP DOCUMENT
-------------------------------------

HOW IT WORKS:
-------------
In order to solve a quartic equation, one must follow a labyrinth
of steps. Solving one by hand could take about ten minutes for even an
experienced mathematician. Quartique does all the same steps any
human would do, but much faster.

To begin with, the x^3 term is eliminated from the equation using a
substitution method. Then, by solving a few linear equations and a
cubic, two quadratic equations can be created. These quadratics
yield the altered roots of the original quartic.

FEATURES:
---------
- 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 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

- Quartique is also equipped to solve cubic, quadratic, and linear equations...
	... to do so, enter a coefficient of '0' in the 'x^4' term in order
	    to enter a cubic equation
	... enter a coefficient of '0' in the 'x^4' and 'x^3' terms in order
	    to enter a quadratic equation
        ... or, enter zeros in the 'x^4', 'x^3', and 'x^2' terms for a linear
	    equation

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.

- In most cases, if a coefficient of a high power of 'x' is quite large, the
  complex roots generated will be off.
