Vector Solver
Allows you to solve vectors either by the X/Y or by the degree and magnitude.

TI calculator programs.
Triangle Solver
Triangle solver. This appears to be a somewhat recent app and I can't remember how to work it (the last I remember, it did work). Its menu driven (but not by the TI-85s built in menu – just standard text menus).
Temperature
It appears to be a useless program at first. Actually, this is handy if you have a Radio Shack thermister and a multimeter. Use the multimeter in Ohm reading mode and attach it to the thermister. Then plug the reading in to this app to determine the temperature. The only problem with this is most thermisters are not exactly alike so your mileage might vary a little.
Target
Here's another incomplete game. It might work, but then I forgot how to play it. There's a box. You must figure out the angle to hit the box (press Enter to input the angle). After that, its not clear what happens. Good luck!
Slope
Here's another one of my favorite apps. Its gotten a lot of mileage and originally started out on a TI-81. It asks for X1, Y1, X2, Y2 which is typically in a text book as (X1, Y1), (X2, Y2). Plop the 2 coordinates in and it tells you the slope (M), distance between the two points, and the X and Y intercepts (if available).
Secant
One of several Trig apps. This one displays how to find the secant as well as lets you plug the numbers in for the calculator to solve.
Russian Roulette
I honestly couldn't remember if I wrote this one or not. But I misspelled the file name so I'm guessing I did. Its great to amuse friends with this.
Radians to Degrees
Quadratic Equation Solver
Give it A, B, and C and it spews out all sorts of nifty info regarding the equation. This app was originally done on a TI-81 and perfected over time. If its a valid equation producing two real numbers, then it will let you know if its a parabola and if it opens up or down as well as the exact points it crosses the X axis and the vertex point.
Pathag – Pythagorean Equation Solver
Although the files are misspelled, this is one of my favorite programs and was originally created on the TI-81 (this version uses the nav menu feature so its no longer TI-81 friendly). The help button shows you the equation in its standard triangular form as well as the graph/cicle form. Select which variable you wish to solve for and the program will prompt for the other two and then solve for the third (or the one you selected).
NegBin
Negative binary representation. Takes a number and assumes its negative and then converts it to binary using 2's compliment and such. The 6 and 8…. are place markers to show the 8th bit and 16th bit. Handy for Discrete Math.
Morph
This program always entertained me (doesn't take much, I know). It asks a range which defines how much of the calculator screen it uses as the display. This was done because setting it to 10 (or full screen) can take some time to produce cool patterns (don't worry though – it will). Change the range to suit your mood. Black lights not included. The patterns are created by randomly toggling pixels on and off. Press Enter at any time to quit (it will leave you in graph mode). Oh, with out the range parameter, this program is not too difficult to memorize. Once memorized, find your favorite TI store and plop it on there (I've only done this once or twice). You will impress your friends and family as well as kill the poor batteries. You didn't hear this from me though… This program requires Clear Axis to be installed.
Mobile 2
Here's what the test mule (named Mobile) turned into. I must say this game is sucks and is not complete (nor do I intend to complete it). The idea is you have to find the portal within so many moves (I think). Use the 4 arrow buttons and 2nd to exit.
Mobile
The train of thought says this was a test mule for a possible game idea I had. It allows you to move the 'O' around using the 4 arrow keys. Press 2nd to exit.
KM – Knots to miles per hour
Converts knots to miles per hour and then figures out the mach speed (doesn't take into account altitude). Handy for quick referencing speed in your favorite flight sim.
Keyboard Key Press Value Finder
Not really sure how the word keyboard got in the name, but you press a key and it reports the key value. It doesn't handle 2nd and then whatever key press. The program constantly scans for keypresses. Pressing the up arrow key will exit the program.
Interest Calculator
I think I needed this app for my intro to economy class. Plop in the interest, time, and amount of cash and it returns what it would be worth after the specified time as well as what you would need to reach the specified cash amount.
Imaginary Number Calculator (i^x)
Calculate i^x where x is a number you supply. It will display the decimal value as well as convert it to a pretty looking fraction. Also included are some notes regaring i^.
Hours
This program lets you play with the number of hours you work each day (handy for the part time folks and for the full time folks, just put 8 for each day in the week). It will total up the hours for the week and calculate your pay (before taxes). This program lets you modify the individual days of the week (including Sat and Sun).
HexDec
Converts hex decimal numbers to decimal notation.
