Polynomial Solver


Display Iteration trail	Verbose Mode

Version: 1.10b
Explanation: Enter a polynomial. e.g. x^3-3X+4 and hit the Solve Equation button. The coefficients can be in ascending or descending order. e.g. -1.2+3.5x^3+4.5x-1.2E-1x is valid.
Floating point in standard notation with e or E as exponent is OK. fx. 120 1.20e2 12E+1 1200E-1 all represent the same number 120.
Verbose print out details about the each iteration steps, if checked.
There should be no limitation of the polynomial degree it can solve.
Complex coefficients can be entered with surrounding () e.g. (3-i4)x^3+(-2)x^2+(-i4)x-(3). Note that all coefficients for a complex polynomial has to be within () regardless if the coefficient is real or complex or implicit.
The Test button setup a default polynomial (for testing only). Version 1.9 adds iteration trail display.
Email: hve@hvks.com if you have any questions.
This version has been tested with both IE7 and FireFox 2.0 browser.

Corrections:

30-Oct-2007	Complex coefficients with an implicit value e.g (i) was interpreted as i0 instead of i1
29-July-2007	Now roots point in the graphic display will also be printable
12-July-2007	A bug has been fixed for polynomial with roots of zeros.
07-Dec-2006:	A small FireFox 2.0 bug was corrected on Dec 8, 2006. The problem was that separation of sign and arguments was not done correctly due to a differences in the Regular expression split function. (Thanks to Brian Phelan for making me aware of the problem and providing the fix)

Note:
If you are reporting a bug:
1)Add an Email address. (in case I have questions)
2)And the polynomial your are trying to solve. If I can't get a detailed bug report I can improve anything! (Please help me out here)
