2. ### Calculus Program

This Calculus Program is designed to assist students with the topics of calculus. The topics are based off of an AP Calculus BC class so that both AB and BC topics are included such as limits, L'Hopital's, related rates, Riemann sums, parametrics, polars, series, and more. The program includes specialized functions such as text wrapping, custom notes, and a customizable formula solver. Both a program and an app are included in this download. The program is compatible with monochrome and color calculators (TI-83/84/+/SE/CSE/CE). The app is only compatible with monochrome calculators (TI-83/84/+/SE).

7. ### Equation Solver

This is a TI-Basic program that when you type in the variables for certain math equations, it gives you the answer to the math problem. It includes several Algebra Equations including slope, Pythagorean Theorem, distance, midpoint, and quadratic. It also includes geometry equations too.
Edit: I added more options to the quadratic. Conversion planned. You can also find the nth number of the Fibonacci sequence. I hope you enjoy...

17. ### 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

21. ### Newton's Method(Calculus)

Pieman7373; Newton’s Method
This program was initially created in November 2016 by Kaleb Allinson (My AP Calculus teacher), but i looked at the code and said that i could make it more user friendly to normal (non-calculator savvy) folk, so he let me. This program is for using Newton’s method of finding the x-intercept(s) of a function in Calculus. THis program will work on the TI-84+(SE), TI-84+CSE, and TI-84+CE calculators. Enjoy!! :D

Categorized under:
22. ### BaseConv 1.1

This program can convert to and from any base between base 2 and base 36, using the appropriate alphanumeric notation. Uses a custom algorithm that should be relatively fast, and can handle numbers up to 10^99. v1.1 fixes a bug that went unnoticed for 11 years.

Categorized under:
23. ### Slope Field v1.2

Slope Field v1.2 simplifies the process of creating and analyzing slope fields in calculus. This program provides a variety of tools for slope fields: you can enter a differential equation, render the resultant field, edit the window settings, find the slope value at a specific (x,y) point, and trace an antiderivative over the field to verify that it is correct. Doors CS v4.0+ optimized.

24. ### 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.

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)

28. ### Horner

So here is the update of Horner. Basically this program factorizes equations of the type ax³+bx²+cx+d=0 as far as we would be able to go ourselves. Have fun trying it out. The updates are notified in the ReadMe.

29. ### 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.

30. ### Right Triangle solver

This program will solve for the unknowns of a Right Triangle with only 2 knowns. Example: 2 sides, or 1 side and 1 angle, with that it will
solve for the unknowns and display them. For any unknown value input "0" zero and press enter to continue the program. Hope you like
it.

38. ### Polynomial Arithmetic Utility

A handy little program to make addition, subtraction, multiplication, and division of programs very easy. This program uses optimized algorithms for multiplication and division and is surprisingly fast.

As an aside, any developer who owns a model other than a TI-84+ SE and wants to clock that program doing polynomials of varying length, feel free. I am looking to compile a time graph.

Update: This program now support direct input of the polynomial, as a string, exactly as you see it, and outputs in a similar fashion.

Note: Negative exponents and fractional exponents not supported.

Categorized under:
42. ### 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.

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.

44. ### TI-Freakware's Converter

This is version 2.0.4 of the TIFC. The previous version only supported roughly 68 conversions, took 4 programs and a picture variable, and was around 6kb in size. Version 2.0.X supports the usage of a single program, and boasts 708 conversions available in this single program of just over 7kb in size. It is also available for the TI-73, TI-82, TI-83, TI-83+/84+ and TI-84+CSE, with the potential of being programmed on other calculators at a later date.

Categorized under:

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.
