  4. CHEMOS is meant to be an all-in-one chemistry helper. All of the equations included are ones that *I* have learned in high school so if there are any that I have not included but you may want me to add, just PM me. Instructions are fairly clear, but if any help is needed, there is a help page on the main menu.

  5. Frustrated with those long equations? need to know the final velocity of a flying potato, but don't think your answer is correct? Then this is the program for you! simply identify the variable not used in the equation (acceleration, time, etc.), plug in the values of the remaining variables and put X for the unknown.

  9. Track any satellite in real time!
    Orbit84 allows you to see the path of a satellite in real time.
    For example, with this program, you can find out if the ISS is currently visible,
    or follow a HAM radio satellite to see if it's reachable.
    This program uses many complex algorithms, such as SGP, to find the precise position of a satellite and display it on a beautiful color map.

  10. This Program will allow you to take full advantage of the clock, date, and timer features of our caculator, without needing to know any of the tedious syntax for the functions. It allows you to Set the Time and Date, view a real-time clock, use the built in timer, and preform many complex calculations, including:
    -finding the Day of the Week
    -converting a large amount of seconds to Days, Hour, Minutes, and Seconds
    -finding the amount of days between two dates
    -and much more!
    This will NOT work for TI 84-Plus CSE, as the menu bug (seen in the screenshots) will make it very hard to use

    Sorry about the error bug in screenshots,I had to use a TI-84 Plus CSE emulator, and those still have the menu bug. THe program looks fine on the 84 Plus CE, however.

  11. 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.

  12. This software is made by JustinYD88 ( You may distribute this software, provided this notice is included. If the software has been edited in any way, please provide appropriate notice.

    This program simulates gravitational interactions with m1*m2/d^2 and F=ma. The demo is included in the program, but you can make your own gravitational configurations by editing the [H] matrix and loading it with the 'LOAD [H]' option.

    Matrices are used to represent the objects. Each row represents an object (up to 99, the matrix limit) and each column represents a property of that object.

    Column 1: The mass of the object (negative masses work too)

    Column 2: The current X-position of the object
    Column 3: The current Y-position of the object

    Column 4: The current X-velocity of the object
    Column 5: The current Y-velocity of the object

    Column 6: The previous X-position of the object (used for drawing lines, internal use)
    Column 7: The previous Y-position of the object (used for drawing lines, internal use)

    Column 8: If circle drawing is enabled, this is the radius of the circle. (If you leave 0, the radius will be (3*mass/4pi)^1/3).
    Column 9: This is the colour used to render this object's circles and lines.

    This program uses the [G] matrix for internal data manipulation, and the [H] matrix for importing configurations.

    Included in the ZIP is the program file, one custom configuration, and two screenshots.

  13. MCAT, a formula used in
    chemistry to find the amount of heat gained or lost in a reaction. This program currently supports finding q, m, and C. Future versions will support Delta T.

  14. Nuke Simulation is a very involved and fun program. It is a program that simulates detonations of nuclear weapons, and you can view to see what it takes to detonate a certain area. There are many different types of bombs, and you can blow things up from a small towns to entire universes! I hope you like this program!

  15. In messenger RNA, a set of three bases called a codon code for one amino acid. With 64 combinations of bases and 20 different amino acids, memorizing what codes for what is impossible and why use a weird, hard-to-read paper chart when you could use your calc! Just use the arrow keys to change the bases and the amino acid abbreviation will appear magically before your eyes! This might work for the Ti 84 Plus but I have not tested it yet.

    (Disclaimer: requires a small amount of understating of how codons work.)

  21. 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.

  22. 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.

  23. With this program written in TI-BASIC you can calculate the day of week for any given date!

    When you try to calculate on what day of the week a date was using the DayofWk( command, you might have noticed that the answer wasn't correct.
    I don't expect you'll have seen that though, but I've tested it with several dates and I can tell you it isn't correct.
    If you want to know more about this, you can read the 'readme' file.

    I've in this program made a settings part, in which you can set everything for your country.

    I really want to thank one of my classmates, who can calculate a day even out of his head, also for the Julian calendar.

    current version: 1.2.2

    -I really recommend checking the 'lite' version of this program if you want a smaller one:
    -There are some important notes for some country's noted in the 'readme' file!

  24. 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.

  25. This is probably the best of all three versions of this program that I made!
    This is a lite version of the day of week program, which calculates the day of week of any given date.

    When you try to calculate on what day of the week a date was using the DayofWk( command, you might have noticed that the answer wasn't correct.
    I don't expect you'll have seen that though, but I've tested it with several dates and I can tell you it isn't correct.
    If you want to know more about this, you can read the 'readme' file.

    There are some important notes for some country's noted in the 'readme' file!

    Current version: 1.0.0

  26. The Julian Date Converter is a very simple program that will accurately converter between the standard date
    (Month, Day, Year) and the Julian Date. This program will also allow you to convert from the Julian Date to the
    standard date.

    Categorized under:
  27. This program takes a measurement (a value and a metric unit) from the user, and provides the user 2 pages of 10 or 11 conversions of the initial value, making it convienent for the user to find a converted measurement they are looking for. Supports all the way from yoctometers (ym)/yoctohertz (yHz), to yottameters (Ym)/yottahertz (YHz). (The user can specify the unit of measurement.) The program is very small and relatively fast! Make use of this if you have science or math homework!

    Categorized under:
  28. With this program you'll be able to convert date formats!
    It can convert to and from Julian day numbers and Ordinal date codes. It can also convert Julian dates to Gregorian dates and reversed!

    Very much thanks to RoccoLox Programs, for allowing the use of his program!
