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.

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! Best so far Excellent in performance and reliable. Except I can't get solutions at intersection of graphic functions.
Mathlab Apps, LLC February 21, 2015
You can see the coordinates of intersections. Look at this picture with 3 steps how to change settings: http://s16.postimg.org/5oye2ax3p/set_graph_1.png Look at this picture with 3 steps how to see the coordinates of intersections, roots, and critical points: http://s3.postimg.org/eejq2env7/set_graph_2.png Click the button inside of the red line. Mathlab Apps, LLC February 25, 2015
The video (8 min) shows how to use the app: www.youtube.com/watch?v=doIYR6hUCpg The User Manual online: http://help.mathlab.us The PDF of the User Manual to read it offline: http://help.mathlab.us/uploads/1/4/4/1/14418664/graphing_calculator_by_mathlab.pdf bought it because you deserve it A damn calculator costs over 10 times this price, and the free version worked offline, keep up the great work. PS: fraction answer option would be nice, along with standard engineering constants. I see another user suggesting this and I saw your reply, but waiting for implementation.... Again brilliant app
Inability to use full logarithmic functionality There is an inability to put a decimal in for the subscript of a log, not to mention that putting in a log with a different base is difficult because it isn't viewed as logx it is log2 then you must delete the 2 from the equation bar and add in your own base. This is quite a disappointment for an app I paid several dollars for. Otherwise it's good.
Mathlab Apps, LLC February 3, 2015
The app counts logarithms with any arbitrary (positive) base. Look at this chapter of the User Manual: http://help.mathlab.us/28logarithms.html Try to enter log[3](9) or look at this picture: http://s8.postimg.org/f7ba23ped/log.png Good I like it. It does everything I want. The only problem is sometimes it can take me several minutes to figure out how to do things.
Mathlab Apps, LLC February 7, 2015
To use the app with more confidence to figure out how to do things, watch the video (8 min): www.youtube.com/watch?v=doIYR6hUCpg Look at the screenshots of the User Manual online: http://help.mathlab.us or the PDF of the User Manual offline: http://help.mathlab.us/uploads/1/4/4/1/14418664/graphing_calculator_by_mathlab.pdf Worth the money The DRM is weird however and forces me into free mode these days, could really use getting that fixed... ("ERROR_SECURITY". I have a lot of tools of all sorts, I debug things. Can it at least tell me what tools it hates? The software, not you here, of course. Like, ERROR: you need to delete com.android.ithinkthisisabadapp )
Mathlab Apps, LLC February 3, 2015
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. Very nice calculator, also for simple equations I like this calculator and the possibility to store your own formulas and constants. It would have been very nice if the most common formulas and constants were stored by default (eventually in 2 sections: standard/own). I hope this feature will follow (for the fifth star).
Mathlab Apps, LLC December 28, 2014
Thank you for your input, Lukas :) Yes, we are preparing the list of standard constants right now. Hope, the next update will have them. Seem to be a great app I have yet to test it properly; however it gives a good impression. It is easy to use. I can recommend it.
Mathlab Apps, LLC December 26, 2014
We are glad you like the app! The video (8min) shows how to use it: www.youtube.com/watch?v=doIYR6hUCpg Here is the User Manual online: http://help.mathlab.us Here is the PDF of the User Manual to read it offline: http://help.mathlab.us/uploads/1/4/4/1/14418664/graphing_calculator_by_mathlab.pdf The description of the last features is not there yet Mathlab Apps, LLC January 13, 2015
Watch this video www.youtube.com/watch?v=doIYR6hUCpg from 6:35 to 8:05. Also look at this picture: http://s28.postimg.org/kee69hqil/Intersections.png Click the button inside of the red circle in the picture to open up the options. Must Have App. Unlike my Nexus 5, I don't always have my TI89 (preTitanium, updated ROM, powered by Eneloop AAAs) with me. For these occasions there's Mathlab Graphing Calculator PRO/EDU.  I'm a professional in the IT field with many related technical hobbies and interests which make use of a variety of calculations on a regular basis, so having an advanced calculator with me is very handy.  This app. is well worth the price I paid for it and I highly recommend it if you're in need of an advanced calculator.
Simple to use and powerful I was using an emulator before. This is much more intuitive and friendly to use by comparison and, of course, takes advantage of the phone's superior screen. As a scientific calculator it doesn't quite match the range of functions on, say, an inexpensive Casio 991ES but there's potential for updates with new features and it's much better value than even the most basic device. I'd really love to see this develop into something like the mobile equivalent of Microsoft Mathematics.
Mathlab Apps, LLC December 25, 2014
Dear Gerard :) We are glad you like the calculator. Please share your opinion about what range of functions it doesn't have as a scientific calculator? Our email is calc@mathlab.us What's New
2D scatter plots, enter coordinates in square brackets [0 1 2 3], select checkbox to show linear regression.

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 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.

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 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.
