I'm not sure about you, but my calculus teacher told me there was no way for my calculator to calculate the area between curves at the touch of a button. Well, these TI89's are off the chain but I've come up a with a nice little patch that lets our little beaut's perform just the same. ** Entering equations If both Y1 and Y2 are populated, curves will choose those two equations and find the area between them. If one or more are blank, you will be prompted for both. *** Change your mind? Press `Y=' during calculations to change the equations, or `TRACE' (window) to change the domain in which intersections are calculated. ** Caveats I wasn't in class long enough to make this program sophisticated enough to comprehend vertical bounds, or know how to react if only one equation was within range of the window. This program will function just fine if you can see everything of interest on the graph, so just use those settings and let this do its magic. ** Output After calculation, the totaled area will be shaded, the final answer stored to Ans, and a message will be printed on the screen. |

It eats up a ton of memory while you're running it, so you may need to either archive things, or set the resolution to "low". This update cleans up a couple of minor issues and also includes some screenshots. |

| **spar.zip** | 1k | 10-03-29 | | **Super Parametric** Two inputs, three outputs. That simple. Any suggestions are welcome via email. |

| **statgraphv2.zip** | 1k | 03-11-12 | | **Stat Graph v2.0** This program graphs data as a scatter plot graph. It does everything for you; it finds the best equation and puts into Y=, it sets the ideal window, and it graphs it! All you have to do is enter the x values and the y values! Enjoy. |

| **tablex.zip** | 1k | 11-02-22 | | **TABLEX 0.4.1** An intuitive table that has more unique features than TI-Table. It has the ability to scroll up, scroll down, page up, page down, choose a y= equation, and can enter an x value within the table. DoorsCS7 is needed to run the program. |

| **transformations2.zip** | 1k | 13-03-19 | | **Transformations 2** This program is different from my first transformations program in that instead of asking for A, B, C and D in the form: Af(Bx-C) + D, it asks for this information in a listing style format. So if a problem is something like: Given x^2, perform the following transformations... this program will may be helpful. IMPORTANT NOTE: This program assumes the order of applying transformations to be: 1) horizontal shifts, 2) horizontal rescaling, 3) vertical rescaling, 4) reflections, 5) vertical shifts. So if the problem does not ask for the transformations to be applied in this order, then the program will not produce the correct graph in general. This ordering is usually the ordering used when transformations are not specified in a given order. Great for teaching transformations. Enjoy! |

| **transformations.zip** | 1k | 13-03-19 | | **Transformations** This program demonstrates how transformations work. The user enters in a base function and then the values A, B, C and D for the form: A*f(Bx-C) + D. It is designed to demonstrate what each value does to the graph. The program will graph each transformation and compare to the original base function's graph. Great for teaching transformations of graphs. Enjoy! |

| **ugraph.zip** | 3k | 00-10-04 | | **Ultimate Graph Utility** This program contains an X= editor, Y= Editor, a special function that increases the precision and decreases time of graphing by about 2 times. Then we still have the graph on and off function and the reset default function. This program is a must have for all students. |

| **ulam.zip** | 4k | 13-03-23 | | **Ulam Spiral Generator** This program draws an Ulam Spiral on the graphscreen of your calculator. Ths program works on both Color and non-color calculators. |

| **variate.zip** | 1k | 07-01-13 | | **Variation Chart of ANY function** This program take the function stored in y1 and displays the variation chart (according to the derived function). User-friendly and precise. It is possible to change precision settings to make the program run faster! |

| **visualpro.zip** | 2k | 07-02-18 | | **Visual Pro** This program will show you a visual represtation of rectagular approximations such as LRAM, MRAM, RRAM, Simpson's Rule, and the Trapeziod Rule. There are also a couple of extras added. |

| **wavegrapher.zip** | 3k | 04-06-15 | | **Wave Grapher v1.02** Wave Grapher is a cool program usful for Math and Physics. It allows you to graph the two equations of two waves using very simple queries. So instead of having to know the complex trigonmoetirc eqution, you only need to know what the amplitude and period is; making it much easier to graph! Also, once the two graphs have been graphed, they you can solve various things with them and you can see what happens after the waves have interfered with each other - so for those who know physics - what the resulting wave or graph will look like after the original 2 have undergone constructive or destructive interference. Also, you can twiddle around with the resolution, screen size and graph quality! |

| **weirstrassfunction.zip** | 5k | 11-11-02 | | **Weirstrass Function** This program generates the graph of a Weirstrass function to show that a continuous function need not be differentiable. The user enters the number of iterations to use and then waits for a graph to be generated. See the accompanying pic to get an idea. Enjoy! |

| **xequalsti83plus.8xp.zip** | 1k | 07-02-18 | | **X Equals Function Grapher v1.0** This powerful tool allows you to graph equations using X= instead of Y=. The program is completely BASIC and draws the lines relatively quickly. Works for linear and nonlinear functions. Check for later versions including tables and trace tools. |

| **xequationgrapher.zip** | 1k | 05-09-09 | | **X= equation grapher** yay! another x equation grapher! this one is pretty good, though. after graphing, it allows you to graph again, calculate specific values, change the graphing resolution (higher number = faster, but less accurate, graphing), clear the screen of graphs, or quit. PLEASE REVIEW AND/OR RATE THIS AND MY OTHER PROGRAMS. THANK YOU! |

| **xeq.zip** | 5k | 09-07-20 | | **prgmXEQ BETA ** This program lets you graph x= and y= equations at the same time. Also has the ability to trace function and view a table. Fixed a rendering issue with the readme file |

| **xgraph.zip** | 1k | 01-05-31 | | **X=Grapher** This is an X=Grapher. |

| **xyinter.zip** | 1k | 10-01-19 | | **X Y intercept** This program finds the X and Y intercepts of a line, when you input the slope and Y intercept. It then graphs it and shows you all the work it did. First program I thought was worthy, hope you like it |

| **ymxb.zip** | 1k | 10-03-18 | | **Y=MX+B** Y=MX+B is used to solve for any variable in the aforementioned equation. If you want to solve for y, hit y. Very straightforward. |

| **zeroes.zip** | 3k | 13-02-11 | | **Zeroes** * Zeroes Zeroes is a program to display all the zeroes of a function (Y1) across the current visible window. ** Invoking Zeroes Feeding information into zeroes is simple. If Y1 currently has a value, zeroes will use that value as its input. If Y1 is empty the user will be prompted for an equation. ** Examining the zeroes To examine the zeroes, scroll the list left and right with the arrow keys. ** Changing the domain or function At any point during the examination of data, press the `TRACE' key (or windows) to adjust the window, or `Y=' to adjust the current function. ** Quitting Press enter to quit zeroes. |

| **zoomworks_84.zip** | 7k | 01-05-30 | | **ZoomWorks & MoveWin revision 3** Allows relatively easy manipulation of the TI 83 and 83plus graph, and moving around in in it. |

| **zoomworks.zip** | 4k | 99-10-27 | | **Zoom Works and Move Window** Save, restore, move, and generate proportionally correct windows. Many features and pretty good docs. |
