Description
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 highquality 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.

Works absolutely perfect! Why pay $85.00$100.00 for a graphing / scientific calculator when you could spend just under $4 for something that does the EXACT same thing?!? It does EVERYTHING as promised, NO crashing, NO freezing and it's so stinking easy to use! I think I have maybe only written reviews for three products total, with this one being the third. That's how unbelievably awesome this app is! So THANK YOU sooo much to the developer of this app for creating such an AWESOME and unbelievably AFFORDABLE product!
Tim Chandler
Awesome app, best calculator on the market place. One of my favorite features is the ability to save functions. I can make my own conversions and really simplify some complicated calculations. Only thing that is missing for me is the ability to use it windowed on my tablet.
Michael Rector
Pretty good app Been using the free version for a while and decided I wanted to give them my money. Threw my money at them and am enjoying the app. A few features missing which make it less powerful than my emulated ti89 platinum, but in all honesty that isn't a huge deal. The addition of solving derivatives, indefinite and definitive integrals, along with some other calculus features would be an improvement which would result in me cranking this rating up to 5 stars.
Justine Me
Flawless! If you are taking Statistics and cannot solve an equation with this calculator, YOU haven't learned all that it can do yet! Read the manual in Adobe because this calculator "woke up like this". #flawless #usererror
Dun Ning
Best calculator on Android, 2015 Probably the best Android calculator in my opinion, year 2015, though by no means perfect. The reason is b/c: 1) it supports multiwindow, 2) it supports graphing ability, 3) it is a scientific calculator with constants commonly used in math. I've tried various calculators and none has all of those things in one package.

Mathlab Apps, LLC March 18, 2015
Dear Jessica! Thank you very much for your nice feedback and financial support to develop the app. The app is still not perfect because it needs additional modules for integrals, limits, and statistics that we are working on to implement. We share what we have and try our best to make the app even more convenient tool to comprehend math with ease:) Awesome app, best calculator on the market place. One of my favorite features is the ability to save functions. I can make my own conversions and really simplify some complicated calculations. Only thing that is missing for me is the ability to use it windowed on my tablet.
Mathlab Apps, LLC March 26, 2015
Thank you for your input, Tim. We'll think how to make the option to show the window with your functions offering to choose them. If you have your own vision and probably design how this window might look at in the screen, please share. You may use the screenshot to draw this window.

Hi Michael! Thank you very much for buying the app :) By the way, you can use it to count derivatives: http://help.mathlab.us/211derivatives.html Best calculator on Android, 2015 Probably the best Android calculator in my opinion, year 2015, though by no means perfect.

Dang near essential This app has been an integral part to passing my math courses since I discovered it last year. I recommend it to everyone I know who struggles with math.
Mathlab Apps, LLC March 25, 2015
Thank you very much for your nice feedback, Cody! We are so happy that you and everybody who starts to use the app become more and more skillful and confident in math ! Congratulations! Amazing Does everything you need for the cost of nothing. Free version is just as good, but it is worth paying to give the congrats and props for such an awesome program.

ERROR_SECURITY means that you have tools that block license verification. Uninstall or turn them off at least. Tools that designed to get paid apps for free. If it does not work for you, we will refund your purchase.
...
It does not check for specific apps that you might have installed. The app does not even have permission to do that. Mathlab Apps, LLC March 15, 2015
If it does not fit on one line, use variables just like in your own example. A=[[...]], then use A on next line. That way you will not have to repeat it again and again. If you need column vector, don't forget to transpose it b^T. Vectors are row vectors by default. Perfect Nothing beats this app. Took a while to get used to but now I've got the hang of it, definitely a life saver!

Im going to stick to MathStudio.
Mathlab Apps, LLC February 21, 2015
Hi Zack. Thank you for your input. We'll implement negative factorials and time graphing with motion. For now, the app does everything that is promised in the description. By the way, the app plots parametric equations, for example, x=cos(t), y=sin(t): http://s4.postimg.org/y5wbcvgp9/Parametric.png Absolutely helpful, suggest to everyone This a great application to help everyone with many different aspects of math
Mathlab Apps, LLC September 8, 2014
Yes! It is the easiest practical way to understand math! The curiosity to enter random functions to see how they turn out helps to comprehend concepts and methods with ease! It's time to get Agrades only for all of your math courses. Best Wishes! Mathlab Apps, LLC March 10, 2015
Look at the map of the keyboard carefully once, try to understand the logic of its organization, then it stops to confuse you anymore: http://s10.postimg.org/gvhlgh5q1/kbd_map4.png Best so far Excellent in performance and reliable. Except I can't get solutions at intersection of graphic functions.

Free Graphing Calculator
Free Graphing Calculator
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
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 any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6) Forgot the quadratic formula? Or the doubleangle 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.
I'd love to hear your comments or suggestions. You can write me at the email address in the app. Thanks!

Wabbitemu
Wabbitemu creates a Texas Instruments graphing calculator right on your Android device. Wabbitemu supports the TI73, TI81, TI82, TI83, TI83 Plus, TI83 Plus Silver Edition, TI84 Plus, TI84 Plus Silver Edition, TI85, and TI86. 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/ti84plusfamilyti83plusfamily#view=mathapps. 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 'Rerun setup wizard'. As you go through the setup make sure you have selected OS 2.55 MP on the OS selection screen.
