User reviews

good graph tool for basic math This app is a very good tool to study simple graphs and to analyze equations of a line. I like using it when relaxing in bed.

Basic euation measuring tool.(Really Amazing) Amazing graphing tool for basic math...Works very sharply to analyze your graph equation..Good to work with...Really amazing...!!!

A very useful Application A good application, very useful for graph equations,really helpful application and accurate. Overall a great application.

Do not be deceived. I thought that this app would let me take a picture of a graph and then use basic pattern recognition to find the axes, grid and an equation approximating the graph. Instead, all that it is is a quick demonstration of point-slope form for linear equations.

## Andie Graph

Get a TI-82, TI-83, TI-83+, TI-85, AND TI-86 emulator for your phone!

Andie Graph is an Android port of the AlmostTI emulator by Marat Fayzullin - http://fms.komkon.org/

*** ROM not included. Why? http://dgmltn.com/roms ***

The TI-8X series of calculators work great as standalone calculators, showing 8 lines of history, using standard mathematical notation. Each model was designed with more specific purposes in mind:

The TI-82 is designed for algebra and trigonometry. Graph and compare functions, perform variable substitution, and solve single variable equations.

The TI-83 is designed for statistics and trigonometry. Graph and compare functions, and perform data plotting and analysis.

The TI-85 is great for engineering and computer science. Graph and compare functions, perform bit manipulation and convert between numeric bases.

The TI-86 is great for engineering and calculus. Graph and compare functions, perform bit manipulation and convert between numeric bases. Solve differential equations, plot vector fields.

All models allow you to write programs in TI-BASIC and perform basic scientific calculator operations.

Follow @dgmltn for updates!

## Simple Graph Drawer Full

The program allows draw functions graphs in specified area. The area is defined by the X min, X max, Y min, Y max values and division values for X and for Y. Functions are defined by the expression string and color. You should click on function string in the table to edit it. Only "x" symbol should be used as a varible. After area and functions data input click "Redraw" button to draw it. On phones graph is drawn on a full screen. Via the menu You can maximize graph on the full screen, get help about functions, about program, save the graph as a picture or sent e-mail with it (with help of mail client app,such as gmail). The advertisement will be shown after the 5 redraws, and may be closed via the menu (or shown). And please, sometimes click advertisement - it may help for developer))).

## Graph It!

FEMA

1

GraphIt is a utility that is used to display on a Cartesian plane any mathematical function, which can be f(x)=2, f(x)=2*x, f(x)=sin(x) ecc... The management function is entrusted to you: you can add more or modify existing ones.

The integration of functions is facilitated by self-completion of statements, also expressions of the interpreter is very flexible and allows the inclusion of any function: even the most complex are recognized and interpreted correctly.

The main functions recognized are: abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), avg(x1,x2,...,xN), ceil(x), combin(x,y), cos(x), cosh(x), e(), exp(x), fact(x), floor(x), lg(x), ln(x), log(x,y), max(x1,x2,...,mN), min(x1,x2,...,xN), mod(x,y), pi(), pow(x,y), rand(), sign(x), sin(x), sinh(x), sqrt(x), sum(x1,x2,...,xN), tan(x), tanh(x), toDeg(x), toRad(x).

The graph allows an accurate view of the trend of function at any point in the plane. You can zoom and pan through the classical gestures.

There is also a tool which can calculate the value of the functions included, given the value of x (via a number or expression).

## 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.

-------------------

Graph89 needs permission to look at your Android Account in order to generate a unique ID shown under F1/About. This works only for TI89/V200. Note that there is no internet connection required for this App.

TiEmu, TilEm and Graph89 have been developed independently of Texas Instruments and are not affiliated with TI.

Texas Instruments and TI are trademarks of Texas Instruments Incorporated.

## THE M VENDETTA

It started with curiosity. Then obsession. Finally criminality.

A group of friends suspect that George could be a very dangerous criminal and convince themselves they needed to do something about it. Instead of following legal channels with their suspicions, they incorporate ‘M’ organization to look into the matter. They preferred ‘M’ to the police because they wanted the suspicious-looking George to be subjected to real painful extra-legal punishment if ‘found guilty’.

‘M’ also conclude George is not who he said he was and was most probably a person who would be a danger to them too. ‘M’ overreacts and sends a female agent to murder George. She fumbles and fails to accomplish the task.

George discovers the persons behind the assassination attempt are no ordinary people- they are too highly placed in the social-economic ladder.

Because of his unusual wretched circumstances, George believes no one would buy his story. He decides to lie low, hoping that ‘M’ would soon realize their mistake and let him live his simple life peacefully….

It’s about vigilantism gone out of control.

Chief to the head of 'George Team', Ronnie: "This has been going on for far too long. How much more time do you need to finish this thing?"

Ronnie: "The problem sir is that the subject knows we want him...you know..."

Chief: "So what? Tell me what you are doing to finish this oaf, not what he knows."

Ronnie: "We are working to make him jobless and homeless first. The rest will then be easy."

Chief: "Four years ago, you told me you will complete the job in four weeks. That never happened..."

Ronnie: "Sir, some..."

Chief: "Don't interrupt me! Two years ago, you were to finish the job in 2 months. That didn't happen. Tell me what you are doing different this time."

It’s a book about power exercised without control.

The M Vendetta is work of fiction detailing a vendetta based on false assumptions.
