The purpose of this page has a funny story. Back in the early 2000's, I knew how to code some basic HTML for webpages. This was before cloud-storage services like iCloud or Dropbox. I loved the idea of putting my stuff "on the web" and have it just be easy to get to. Neat idea, right? I was clouding my stuff before there was a cloud. The all the information on the internet are like shifting sands. I wanted prevent some things from disappearing; much of the content in the library section has been made into a PDF or some such file so it will stay put until I delete it. So there you go! Feel free to look around, and I hope the content is useful to you! - Andy

Factoring Numbers Program
A short program written in TI-BASIC for the TI-84 and a program, also written in BASIC for the TI-nspire, will take a positive integer and output it's factors. If the number is prime, then only 1 and the number will result in the output. The 8XP file is for TI-84, and the tns file is for TI-nspires.

Transferring Files onto the TI-84 Plus
A very short video that shows you how to transfer an .8xp file on to your TI-84 series calculator. You will need a laptop or desktop Windows/PC or a Apple Mac. Download some free software from Texas Instruments and install it on your computer. You will also need a USB cable (sorry, the Mini-USB cable you use with your Samsung Smartphone will NOT work). This will work fine with TI-83 Plus but you will need a Silver Graphlink USB transfer cable.

Quadratic Equations on the TI-84 Plus
An essential program for anyone working with quadratic equations in Algebra. This program takes coefficients a,b, and c and produces the solutions, discriminant, axis of symmetry and the graph. Even better, it adjusts the window automatically for you when you view the graph...no more fooling around with xMin and yMax in the Windows menu. No other programs do what this one does! And best of all it's FREE. Need help installing a program? See this vid.

The Standard Shading Program (Normal Density)
This program which works on the TI-84 Plus and TI-83 Plus will take the mean, standard deviation, lower and upper bound to produce a graphe of the area as seen shaded on a normal curve. It will also state the area under the curve. Need help installing a program? See this vid.

Faster Graphing / Asymptote Detection
For many, the first time a function is graphed on the TI-84+ Color it is S-L-O-W. This is because a mode called asymptote detection is set to ON. By turning this off, plotting of a graph is sped up. But why is this mode here? What does it do? View the Youtube video to see and/or view the PDF documentation.

Z-scores and Percentiles
Studying z-scores and/or percentiles? You want this program! Compatible with TI-84+ SE and the newer TI-84+ SE Color. This program will do three things: 1) find a z-score given mean, standard deviation and the raw score, 2) find the z-scores of a list and put them into another list for easy viewing, and 3) find the z-score given the percentile. Yes! Bonus, the listing of the program is in PDF form so you can look it over to see how it works.

How to use the Algebra Equation Solver
This is a built-in utility found on the TI-84+, SE and SE color. The solver allows you to put in an algebraic equation and solve for x. This tutorial shows you how to use it on the TI-84+ Silver Edition Color, and also on the TI-84+ SE which has some minor differences.

Binomial Probability Program
Working on a lesson about binomial distributions and probability? Need to find probabilities using the formula ? This program will take in trials, probability of success, and desired number n and output a helpful summary of probabilities.

The TVM (Time Value Money) App
This built-in APP found in the TI-83+, TI-84+ and the TI-84 C is a financial app that is very powerful and easy to use. This App allows you to solve for Number of payments, Interest rate, Principle, Future Value and payments. This App is worth the price of the calculator alone. Have this with you next time you sit down with a lender.

The MIDPOINT Program
This program will find the midpoint (x,y) between two points, (x1,y1) and (x2,y2). This program and video are designed to help you learn the basics of programming your TI-84 calculator. Download the PDF and learn simple input/output and computation.

 Slider Demo This TI-nspire document (should work with both regular and CAS models) is a simple document which has sliders connected to variables which control a graph. Page 1.1 is a linear equation and page 1.2 is a quadratic equation slider-demo.tns - TI-nspire Document

 Southpark "Math Is...Universal" Poster For fans of the long-running Comedy Central show Southpark, below is a re-creation of that poster seen in the background of Mr. Garrison's 4th grade classroom, the famous "Math Is...Universal" poster. The background image is known commonly as the Keyhole nebula. The font used is called arcon. I had it printed at Walgreen's photo printing services, at a size of 16 inches by 20 inches for around \$25. Download this poster, send it to Walgreens (or other printing services) print, and hang in plain sight! You never know what 4th grader will be inspired...

 Calculator Emulation

 This is a .zip file containing the TI-83 Debugger I've downloaded from Texas Instruments. Included in this zip file is a short video tutorial on how to install it, and run it for the fist time. Student-friendly. Works with Windows 95 thru Windows 10. This program does a great job of emulating the TI-83 Plus and TI-89. Tested with Windows 7. While fully functional, this is more of a novelty/nostalgic item than a useful calculator. It is a simulation of the popular mid-1970's scientific calculator from Texas Instruments. It re-creates the red LED display, the button press sounds, and the wait time for calculating complex expressions. Windows Only. This is a link to the actual site. Wabbit EMU is a Z80 simulator. Highly configurable. Can be used to simulate a TI-83, TI-84 Plus, and TI-84 Color. Windows zip archive, as of March 2015. A fully working HP-12c right on the web! They also have a Chrome App that will open in it's own window and behaves more like a desktop app for \$1.99. Give it a try to get a taste of reverse Polish notation. You can purchase actual Windows/PC and Macintosh app versions from RLM Tools.

# Vector Graphic Sample

The graphic to the left was my attempt at vector-based art. I attempted to copy a raster-based graphic, which was made of pixels, into a raster-based graphic which is made of curves and lines based on equations so it can be scaled and sized without limitation. In a way, this is where math meets art. The graphic can be downloaded as a Photoshop .psd CS5 document, with a "smart object" embedded in it. Enjoy!
