# Description

Wabbitemu creates a Texas Instruments graphing calculator right on your Android device. Wabbitemu supports the TI-73, TI-81, TI-82, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, TI-84 Plus Silver Edition, TI-85, and TI-86. Fast and convenient, Wabbitemu allows you to always have your trusty calculator with you. Because Wabbitemu is an emulator, the calculator it creates will act exactly like the real thing.

Wabbitemu, like all emulators, requires a ROM image. Wabbitemu includes an easy to use setup wizard that will help you create a ROM image for your TI.

Frequently Asked Questions:

1. How do I bring up the menu?

You can bring up the menu by swiping from the left edge of the screen, or pressing the menu key (if your device has one).

2. How do I disable vibration when I tap on a button?

Open the menu and click on settings. Under the 'Skin' category unselect 'Vibrate on keypress'

3. How do I load apps like PlySmlt2 or Inequalz?

To load any file to your calculator you need to first download it to your SD card or internal storage on your device. You can find the official TI applications for the 84 Plus (non color) available here: http://education.ti.com/en/us/software/search/ti-84-plus-family-ti-83-plus-family#view=math-apps. Once you have downloaded the app to your device open Wabbitemu. Swipe from the left edeg of the screen to bring up the menu, and select 'Load file'. Find the file you just downloaded in the list and select it. The file will be sent to your calculator. Apps for the 83+ and 84+ calcs will end in *.8xk. Apps for the 84+CSE will end in *.8ck or *.8xk.

4. I'm missing fraction options when I press Alpha+F1! How do I get these fraction options?

Fraction options (and the rest of the Alpha+FN menus) are only available on OS 2.55 MP. Wabbitemu allows you to download both 2.43 and 2.55 MP. You can check your OS version by hitting '2nd' then '+'. Then press enter to go to the about screen. If it not 2.55 MP or 2.53 MP you will need to upgrade.

To upgrade you will need to recreate your ROM by going through the setup wizard again. The setup wizard is runnable if you bring up the menu by swiping from the left edge of the screen. Then select 'Re-run setup wizard'. As you go through the setup make sure you have selected OS 2.55 MP on the OS selection screen.

More documentation can be found on the official website, http://wabbit.codeplex.com

Works great! Only thing is that it's just that I'm not used to a calculator being touch screen so watch it when you're doing math because you might accidentally tap another number or something and it could go all wrong. But other than that I love it.

Arkmabat -

Loaded my TI86 Rom fine but has problems importing *.86S files Ti86 games in the *.86P format load fine now with the " ASM( " command before the name of the *.86P to execute. I cannot successfully load *.86S string files though still which is necessary to play old ION TI83 games on the TI86 through the use of ION86. Please fix. Thank you.

eliseo balbuena

Perfect Very useful for when you forget your calculator at home. Takes time to get used to the touchscreen buttons though. Its perfect once u get used to it.

Alex H

Sweet! I love having a copy of my good old TI calculator with me wherever I take my tablet. Very convenient.

Izzy Beth

Good but glitches I use this calculator for statistics and it works well except that sometimes it freezes and I have to completely stop running the app in order to use it again. This time I was calculating the standard deviation and it completely froze to the point that I had to uninstall the app. Other than that, it's great and hey, it's free!

Savannah Loera

It's great! I just downloaded this app to use in class and it looks just like the original calculator! I am using the TI 83 Plus and it has all the same buttons and functions as the real thing. In the beginning just check the option that says you don't have a ROM file and then it will take you through the process to download the file and you have a free TI calculator :-)

User reviews

Stability issues on Lollipop Works mostly fine for my HTC One M8, it's just that the ROM selection and creation screens don't show anything, so you can't select which ROM you want. But once you get past those screens, the app works almost perfectly (it has the occasional crash when I open it, but it hasn't crashed while I was using it)!

Great app but please fix Size issue On my phone the calculator buttons take up the whole screen and its awesome. However, on my Nexus 7 tablet there is a lot of unused grey area and the buttons are actually smaller on my tablet than on my phone. I tried clicking the largest skin size button, but it has no difference when it's clicked or unclicked. I also tried on a couple of different calculator Roms but still the same problem. Please fix I'd really like to use this app on my tablet but its hard to click the buttons.

Nice TI calculator emulator but not without its issues I like the app as it emulates more calculators than Andie Graph and it works nicely as a whole but sadly, it can be slow on devices like the Samsung Galaxy S3 mini. PS: Stupid question maybe, but does this app support USB connectivity emulation? The reason for me asking this is because the TI-84 has a PS3 jailbreak application which can be used to help the PS3 enter into Factory Service Mode and it would be nice if USB emulation is supported but root permissions are most likely needed if that is the case.

## Free Graphing Calculator

A powerful, flexible graphing calculator . . . and it's free!

Does far more than most of the paid calculators out there . . . let alone the free ones.

Features:

1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:

• the usual arithmetic functions and exponentiation.

• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.

2) Graphing. Capabilities:

• Graph up to four equations at once.

• Graphs are labeled.

• You can drag the graph or pinch to zoom in or out.

• Calculator can find roots and intersections.

• Graph in polar coordinates.

• Graph parametric equations

• Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this!

3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!

4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework!

5) It can make a table of the values of a function you enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.

6) Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition.

7) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.

8) Statistics -- enter data and make a histogram, box and whisker plot, or scatter plot with optional regression line.

I'd love to hear your comments or suggestions. Because of spammers, my email address is not in this description, but it is inside the app, and it's great to hear from real users.

## Graph 89 - (with TI84 support)

Graph 89 is an emulator for the TI-83, TI-83 Plus, TI-83 Plus Second Edition, TI-84 Plus, TI-84 Plus Second Edition, TI89, TI89 Titanium, TI92 Plus and Voyage 200 calculators.

*Please remember to read the ROM section below before downloading this application!

It will turn your phone or tablet into an exact replica of your calculator. The emulator will provide the same functionality and generate the same results as your real calculator. Being ported to Android means that it will always fit in your pocket, have a backlight, be rechargeable and also run faster.

You would be able to install applications by copying the App file to the internal memory of your phone, pressing the 'Back' button and selecting 'Install Application/Send File'.

Graph89 would be great tool for math, science and engineering courses in high school, college and beyond. Some of these calculators feature Computer Algebra System (CAS) having the capability to simplify and symbolically solve mathematical expressions.

Graph89 combines two powerful emulation engines which make it the only app in the Android Play Store to support the full range of TI graphing calculators.

1) TiEmu - http://lpg.ticalc.org/prj_tiemu providing support for the Motorola 68K family: TI89, TI89 Titanium, TI92 Plus, Voyage 200

2) TilEm - http://lpg.ticalc.org/prj_tilem providing support for the Z80 family: TI 83, TI 83+, TI 83+ SE, TI 84+, TI 84+ SE

!!! IMPORTANT !!!

ROM:

Emulators are computer software which simulate a specific hardware. In order for the emulator to do anything useful it needs some software to run. The software that runs in your calculator (ROM) is copyrighted by TI, and as such, it can not be distributed by Graph89 or any other emulator for that fact.

This means that you will have to provide the ROM file yourself by extracting it from your own calculator. Transfer it to your phone, and then tell Graph89 where to find it. To extract the ROM you can follow the instructions from http://www.ticalc.org/programming/emulators/romdump.html and by using TiLPII from http://sourceforge.net/projects/tilp/files Google and youtube are also great sources of tutorials and help.

Wabbitemu http://wabbit.codeplex.com/ is also a great tool for extracting the ROM from your TI83/TI84

Supported ROM files:

TI89, TI89 Titanium, TI92 Plus and Voyage 200:

*.rom, *.89u, *.v2u, *.9xu, *.tib

TI83 Plus, TI83 Plus SE, TI84 Plus and TI84 Plus SE:

*.rom, *.8Xu

TI83:

*.rom

Firmware updates (*.89u, 9xu, *.v2u, *.8Xu) which are normally used to restore the operating system of your calculator can also be used as a ROM image.

Needless to say, you will be very disappointed if you purchase Graph89 without having the ROM file ready. You will just see some instructions and a blank screen.

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.
