Very limited utility Could find no way to scale axes independently. Not very useful if you can't do that. Cannot use physical keyboard to enter functions. No pinch and zoom at all.

Samvandha Pathak

This is the one every maths student should have I liked the app very much bit can you please add a cursor while editing the typed functions

Jeremiah Nathaniel

WHAT I'VE BEEN LOOKING FOR!! This is the app I've been searching the Play Store for!! It graphs easy and fast! Great for me, a student who is taking Pre-Algebra! Five Stars!! Samsung Galaxy Nexus (Sprint)

A Google User

Helpful Does what it says. Its suits my needs at the time (last year in high school).

A Google User

Extremely limited No Y. On the Acer Tablet can not access the left key area in function area. Makes this limited graph useless

A Google User

Still some work to do Need to be able to edit functions, not just open and add..

Still some work to do Need to be able to edit functions, not just open and add..

Works great for free!!! If you need more out of it, then dont be stupid and buy it. I mean the going rate for a real one is $150. ITS FREE!!!!!!!! DUH

Serious problem Doesn't display parts of functions where slope is near vertical.

Lies Nearly all the stuff it says you can do in the description are actually only available on the paid version. Useless and misleading.

It's pretty good app,but some futures don't work like intersect....:(

Should Mention DEMO Very limited. Can only graph a function & look at it, options for trace, roots, table of values, etc. are disabled.

An absolutely excellent app. Best free graphing calculator on the market by far.

## Graphing Calculator by Mathlab

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.

Free version requires internet connection and contains ads! Upgrade to PRO!

## 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!

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).

## 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.

FAQ’s

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?

A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/

Q. How do I get to the keys for pi, e, solve, etc?

A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.

Q. What do you have planned for future releases?

A. You can keep up to date on the latest news on our blog at http://mathally.blogspot.com/ . This news will include what is coming up in future releases. Also feel free to leave comments and let me know what you think!
