  5. TI-83 Plus/TI-84 Plus BASIC Science 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. Balances chemical equations! Input an equation as a string and chemical equation solver will output a list containing the balanced coefficients. You can imagine its utility in chemistry class.

  3. This is a program for finding pH, pOH, [H+] (Concentration of H+ ions)/ [OH-] (concentration of hydroxide ions). This WILL work on all of the TI-84 series of calculators, untested on the TI-83. All you need to do is input one of the values mentioned above, and the program will calculate the rest of the values. They are rounded to 3 decimal places, for ease of displaying on the TI-84+ screen. If the values go off-screen, or look messed up, please report this by reviewing the file. I will get it fixed and re-uploaded ASAP.

  16. This is a program that allows you to actually simulate objects moving in 2D space. You can make quadrilaterals and circles, set the size, initial velocity, gravity, and air resistance. You can put as many objects into a simulation as your memory will allow; running the simulation will show how the objects would interact.

  17. ParSim v1.0 is a 3D particle simulator application for TI-83/84-series graphing calculators. It can simulate and display 3D static and dynamic electric and magnetic fields as well as particles of all velocities, positions, charges, and masses. The simulator output is displayed in a graphical interface that automatically adjusts for optimal output of the data at hand. It assumes a k-constant of 1, so charges, masses, and velocities should be expressed on the scale of 10^0th integers for the elementary particles.

    1. Subscripts
    2. Parentheses
    3. Long element names
    4. Those numbers that are used to balance equations
    5. Up to 16 individual elements in one formula

    The controls are a bit confusing, but they are listed in the readme and below.

  24. A very simple program that does exactly what it sounds like it does. This program simply has you enter in the three
    numbers and the letter(s) (i.e. 103K or 3R3K) that are shown on a disc capacitor and the program will find the value of that capacitor.
    A very simple, easy, and useful program to have.

  27. A very simple program that does exactly what it sounds like it does. This program has you select the colors of
    the bands on a resistor and then it tells you what the resistance, tolerance, and temperature (for 6 band resistors)
    is of a resistor with those color bands. This program works for 4, 5, and 6 band resistors. This program will also,
    automatically convert the resistance number into Ohms, Kilo Ohms, or Mega Ohms. A very simple and easy program
    to use.

  32. PROJMOT.8xp: This is a very simple physics program for projectile motion problems that gives you Vx, Vy, Tup, Ttotal, and Dh from just
    velocity and angle! As far as I can tell, it is the simplest program out there that will tell you all of these values. It
    gives you the most exact possible values as it doesn't round to a certain amount of digits.

    PMXY.8xp: Same exact program as PROJMOT.8xp, just skipping velocity & angle. Prompts Vx and Vy to calculate your answers.

    The code for PROJMOT.8xp and PMXY.8xp is essentially the same, just with a few tweaks to the solution screen!

    I made these programs because I didn't want to have to plug every single equation into my calculator for physics class.
    That's it.

    Enjoy the program and happy calculating!

    If you prefer your calculator in radian mode, make sure you switch it back once you're done running this program! This
    program automatically switches your calculator into degree mode. To go back to radian, press MODE, ↓, ↓, ENTER.

  35. The Ultimate Temperature Converter! This is a very simple, easy program to use. This program
    that has you select which temperature unit you wish to convert from and then the program will
    give you that temperature in seven other different units.

  36. A very simple yet useful program that just has you enter in an equation (in terms of Y=) and then
    the X value of the tangent line. From there, the porgram will calculate the equation of the
    tangent line for that equation and at the entered X value. This program will also store both equations
    into the Y1 and Y2 variables of the calculator.
