23. ### Polynomials All In One v3

A redesign of my Polynomials All in One math tool. Input is handled using a two-part queue string, separated by a colon. Part one indicates the operators, part two the operands. This program can chain operations, can interrupt normal math to find the zeroes (at that point), and supports derivative and integral as well. Repeated exponents and terms out-of-exponent-order do not confuse the program. Fractional coefficients supported. Negative exponents not supported. Error catching for unsupported features, divide by zero, and algorithm failure implemented. In addition, prepend the input string with "W" or "w" to activate this program's "show work" feature.

2.3 - Zeroes finding algorithm fixed. No longer glitches on non-integer coefficients.
2.4 - Zeroes algorithm debugged, steamlined, and optimized. MIssing zeroes fixed.
3.1 - Options menu added. Show work moved here. Prepending input with W now turns off show work for individual polynomials. DCS/Celtic3 saving integrated (silently disables if not present).
3.2 - Zeroes finding algorithm now no longer fails when trailing coefficient(s) are zero. Rather if realizes that this means some power of X is factorable, drops the trailing zeroes, adds 0 to the set of zeroes, then proceeds with rational zeroes test as normal

24. ### Jury's Stability Criterion Solver

This program computes the Jury's Stability Criterion table given the polynomial characteristic equation of a digital control system. It both determines whether the system is stable (in other words, if the first term of every odd row is positive) and displays the criterion table used to determine the stability of the system. The basis of the algorithm for this program was found in "Advanced Modern Control System Theory and Design" by Stanley M. Shinners, John Wiley & Sons, 1998. It was originally published in several papers including "A simplified stability criterion for linear discrete systems" (Proc IRE 50, 1493) in 1962.

25. ### DERIVE v5.1

This program differentiates any explicit additive algebraic expression in the form f(x)=ax^n+bx^n+..., setting f(x) to Y1, f'(x) to Y2, and f"(x) to Y3.

With the 5.1 update, the program now turns x-terms with negative exponents into fractions. For especially long functions, an estimated time (per differentiation) is given. For more information, see my forum post at (http://www.cemetech.net/forum/viewtopic.php?p=225715)

30. ### Math Program 2.6

This is a great program for anyone who wants to save time finding simple things. This program will find the GCD, give the prime factorization, find the number of degrees between hands of a clock at a time, and much more. There are two new features that are updates from 2.2; Base Conversion and Mod Simplifier. Base conversion will convert between any two bases, 2-62 and will not allow you to imput improper numbers in that base. Mod simplifier will simplify any mod. These are especially useful for contests such as MathCounts, AMC 10/12 and just for general use. Download today! The update from version 2.4 includes 2 new features (Encode & Decode), compressed into 1 program, size optimizations, and minimal archiving and unarchiving. UPDATE INCLUDES BUG FIX ON TEST PRIME! Version 2.5 includes the new feature of finding the distance between any line and any point and also the ability to adjust the size of list prime for people with low memory.

New Features in 2.6 include a secret area and the ability to draw any figure to scale, given the coordinates.

34. ### Polynomial Division v1.0

Written for the same class as my Jury's Stability Criterion Solver, this program performs polynomial division on arbitrary numerator and denominator polynomials. It accepts any pair of n-degree numerator and m-degree denominator, where {n,m}>=0 and n does not necessarily equal m. The program will produce successive terms until a remainder of zero is achieved or the user presses [Clear], whichever occurs first. It is particularly useful for calculating the finite impulse response of a digital control system, and is of course DCS6+ compatible.

Categorized under:
35. ### Oblique Triangle solver

This program will solve an Oblique Triangle, as long as you know any 3 values of the triangle. Example ( 3 known sides, 2 known sides and
1 angle, or 2 known angles and 1 side ). For any value that you don't know, input a "0" zero for that value and press enter. Once you have input all the values the program will display all the angles and sides of the
triangle for you.

This program basically takes the quadratic equation from your mathclass and puts it in a form you can basically copy straight from because it puts the steps right on the graph screen. Does not support negative discriminats. This contains another one of my quadratic programs that doe give imainary answers, but not in a graphical sense. By downloading this file you agree to use it at your own risk, you did it to yourself, not my programs.

45. ### MathGame1.0

I'm sure you all know the famous Nintendo DS game where you have 20, 50 or even 100 simple math calculations which you need to answer as fast as you can. It shows your progress on a daily basis and you have graphs of this progress. Well this should become a similar game for the TI 83/+/SE and TI84/+/SE. This is only version 1.0 and only has the gaming interface. No score keeping yet but still quite nice to play. Only down side, the randomness of the calculations is not that high.

B, and C for the standard quadratic equation f(x)=A(x^2)+Bx+C. This program can
find a GCD and factor it out, even if it is negative. I spent a lot of time
working on it displaying properly. I eventually plan on making a full-featured
quad program that factors, solves, and gives vertexes (among other things).
Feel free to mess with my code (OPENSOURCE ROCKS!!) and share, but PLEASE
credit me as the original author.
