  4. TI-83 Plus/TI-84 Plus BASIC Programs
  5. TI-83 Plus/TI-84 Plus BASIC Math Programs

These programs are for the TI-83+ and TI-84+ calculators, including the 83+ SE and 84+ SE. They are mostly not compatible with the color-screen 84+ CSE or CE variants, but some BASIC programs can be run on all of them.

  1. Sirdudeman's Math Collection Version 0.3.0

    A collection of function solvers useful for math from middle school to grad school!

    This is still in beta so glitches and a smaller library of functions will be here.

    If you have any problems with this or suggestions for functions, tell me!

    Functions:
    - Pythagorean Theorem
    - Quadratic Formula
    - Area Calculator (Triangles, Rectangles, Circles, Ellipses)
    - Volume Calculator (Prisms (Triangular, Rectangular, Pentagonal, Hexagonal), Pyramids (Triangular, Rectangular, Pentagonal), Cylinders, Spheres)
    - Temperature Conversions (Celsius, Fahrenheit, Kelvin)

    Changelog:

    Version 0.3.0
    - Temperature Conversions Added
        - Fahrenheit, Celsius, and Kelvin can all be converted between each other.
    - Version on title screen changed from "v0.1"
    - Versions are now labeled as "0.1.0, 0.1.1, 0.1.2" instead of "0.1, 0.1.1, 0.1.2".

    Version 0.2.1
    - File changed from .8xp to .zip

    Version 0.2.0
    - Quadratic formula now tells you if X is undefined instead of crashing
    - Area calculator added
        - Triangle
        - Rectangle
        - Circle
        - Ellipse
    - Volume calculator added
    - Prism
    - Rectangular Prism
            - Triangular Prism
            - Pentagonal Prism
            - Hexagonal Prism
        - Pyramid
            - Triangular Pyramid
            - Rectangular Pyramid
            - Pentagonal Pyramid
        - Cylinder
        - Sphere
    - "Back" Function added to all menus

    Version 0.1.0
    - First version ever!
    - Pythagorean Theorem and Quadratic Formula added

  2. Minecraft Stronghold Finder (Java Edition only)

    This program efficiently triangulates the position of a stronghold using two position and angle fixes obtained by sighting an Eye of Ender and recording the position and angle from the F3 debug menu. Not compatible with Bedrock Edition because it doesn't show your angle.

  3. Unit Circle

    This is a unit circle that includes sine, cosine, tangent, degree and radians for every 15 degrees.
    Most have exact values.

  4. TINT: TI-Number Theory

    TINT, or TI Number Theory, is a package of lists and programs designed for number theoretic computation and analysis on the TI-84+ series of calculators. These programs are designed to be used as subprograms for larger projects, and are optimized for numbers less than ~10^12. This packages requires OS 2.53MP to run.

  5. Complex Matrix Linear Equation Solver

    If you have a known complex matrix times an unknown column vector and you know the result in complex column vector form, you can find the unknown vector. This is a great help for nodal analysis in circuits.

  6. Area, Perimeter, Volume Calculator

    Simple program created during school and at home.

    Allows you to calculate the area, perimeter, and volume of most but not all shapes.

  7. SPSS Sample Skewness & Kurtosis

    SKEWKURT is a program for calculating univariate sample skewness and kurtosis!

    Note: All formulae are derived from the Statistical Package for the Social Sciences (SPSS).

  8. Quantulator V1.0

    A program that:
    - Calculates Quantiles from grouped dataset, using user input.
    - Draws BoxPlots from grouped dataset
    - Calculates Q1,Q2,Q3 from grouped dataset
    - Uses the basic Menu( function (dunno if that's a feature or not)

    Please read the ReadMe file for instructions on how to use it, and if you're interested in making it smaller or more efficient, I've also shared the SourceCoder3 project inside of it.

  9. Normality Check

    NORMCHK is a program for checking if your data follows a Normal (Gaussian) distribution!

    Note: This Normality check relies on finding the correlation coefficient of the Normal probability or quantile (a.k.a "Q-Q") plot of a variable. There are MANY ways to assess the Normality of a sample distribution; this is one of them.

  10. Extra Math

    Ever wanted to practice your math skills on a ti 84 plus?
    You probably won't but here it is!
    v1.0.0
    Coded in TI BASIC
    Type DONE in the answer selection to quit or press on.

  11. TrigPack

    SASSIDE.8xp: This program prompts side a, angle, and side b to give you the length of your missing side. Simple as that!

    SSSANG.8xp: This program finds every angle inside a triangle by prompting side a, side b, and side c.

    TRIGLAWS.8xp: This program is more of a note program than anything. It displays the equations for both the law of sine and law of cosine. The formulas given are for area using SAS; ASA, AAS, and SSA; SSS for finding angles; and SAS for finding sides.

    TRIGVALS.8xp: This program just gives you sine, cosine, tangent, cosecant, secant, and cotangent values from any given sides.

    DISCLAIMER — Any values using square roots won't entirely work, since TI calculators make square roots decimals rather than simplifying. I'll try to find some solution to this at some point.
