Hi everyone. The purpose of this page has a funny story. Back in the early 2000's, I knew how to code some basic HTML to write webpages. This was before cloudstorage 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 decided to store them online and make a page for me, and anyone else who wanted to borrow my stuff.
It is said the internet is like "shifting sands" and I wanted to keep some things and have them not disappear, so much of the content in the "library" (see below) has been make into a PDF or or some such file so it will stay put until I delete it. So there you go. Welcome to my website. Feel free to look around.  Andy

Transferring Files onto the TI84 Plus
A very short video that shows you how to transfer an .8xp file on to your TI84 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 MiniUSB cable you use with your Samsung Smartphone will NOT work). This will work fine with TI83 Plus but you will need a Silver Graphlink USB transfer cable.



Quadratic Equations on the TI84 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 TI84 Plus and TI83 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 TI84+ Color it is SLOW.
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.



Zscores and Percentiles
Studying zscores and/or percentiles? You want this program!
Compatible with TI84+ SE and the newer TI84+ SE Color.
This program will do three things: 1) find a zscore given mean, standard deviation and
the raw score, 2) find the zscores of a list and put them into another list for easy
viewing, and 3) find the zscore 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 builtin utility found on the TI84+, 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 TI84+ Silver Edition Color, and also on the TI84+ 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
${}_{n}C_{r}{p}^{r}{q}^{n1}$?
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 builtin APP found in the TI83+, TI84+ and the TI84 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, (x_{1},y_{1})
and (x_{2},y_{2}). This program and video are designed to help you learn
the basics of programming your TI84 calculator. Download the PDF and learn simple input/output and
computation.



Slider Demo
This TInspire 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

TI83 Plus Debugger & Instructions 
This is a .zip file containing the TI83 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. Studentfriendly. Windows Only 
Virtual TI (w/ROMS) 
This is a very nice emulator. Requires downloaded ROMs, which are included. TI83 Plus, TI85 (version 9.0) TI86 (version 1.3), and TI89, (version 2.09). Windows Only 
Vintage TI30 Simulator

While fully functional, this is more of a novelty/nostalgic item than a useful calculator. It is a simulation of the popular mid1970's scientific calculator from Texas Instruments. It recreates the red LED display, the button press sounds, and the wait time for calculating complex expressions. Windows Only

Wabbitemu

This is a link to the actual site. Wabbit EMU is a Z80 simulator / debugger which will automatically download a working ROM from TI's website. Highly configurable. Can be used to simulate a TI83 or even the latest TI84 Plus. Windows zip archive, as of March 2015.

Vector Graphic Sample
The graphic to the left was my attempt at vectorbased art. I attempted to copy
a rasterbased graphic, which was made of pixels, into a rasterbased 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!
