# 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 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.

Perfect for people going back to school While this is NOT a graphing calculator, or a fractions calculator, it is an absolutely awesome algebra calculator. Its been awhile since I have been in school, and I just started going to college, and this has helped me with algebra so much since we are allowed to use calculators in class. Best part aside from it actually works, it is free and accurate! I haven't had any issues with it rebooting, shutting down or freezing either.

Reuben Bellotte

Awesome! This app has helped in ways my teacher never came close too! I would type in the equation and this app would spit out the answer almost every time. Then as I worked through the problem step by step the app would let me know if I was right or wrong. Love this app, an amazing teaching tool.

Benjamin Gaylord

Beats the pants off some pay apps! Also beats the pants off my ti-nspire which cost me $90 on sale. This may not be allowed in a class environment but it's well worth the download.

Mya Key

Love it Does anyone know how to make it show the decimal AND fraction answers like it used to?

Mathlab Apps, LLC March 17, 2015

Hi Jessica :) We're glad you like the app. It has 4 modes: (1) Calc, (2) Graph, (3) Table, and (4) Library. Look at how to switch to the Graph mode: http://s23.postimg.org/6bigffre3/How_to_Graph.png First, click on the upper-left button, then choose "Graph". Look at help: http://help.mathlab.us Here is the video: www.youtube.com/watch?v=doIYR6hUCpg Good but I'm confused about how to plot points, such as when I do (-145,1140) (-130,1020) it's shows (-,145?,?1140) (-,130?,?1020) and won't solve or plot the points

Mathlab Apps, LLC March 18, 2015

For 2D scatter plots, enter coordinates in square brackets [-145 1140 -130 1020] For example: http://s18.postimg.org/pdyt2u2e1/dots.png Select checkbox to show the linear regression: http://s17.postimg.org/6z8dquprz/Linear_Regression.png You can plot more than 2 points, of course :)
wtf? ive been looking for a really nice graphing calculator, and i thought i found it but its broken. it cant do square rooted values, and i dont even how what happens when i give it absolute values. great program, bad math

Mathlab Apps, LLC March 25, 2015

Here is an example to count the square rooted value of 4. The second example counts the square rooted value of the complex number (-4): http://s9.postimg.org/gfpf1jh5r/SRV.png If you are not sure how to enter some formula, look at the examples from the User Manual: http://help.mathlab.us It was really helpful except for a problem with supplementary angle's sine where not showing as equal. Fix that and it is perfect. I put sine 120 equals sine 60 and it said false.

Mathlab Apps, LLC January 21, 2015

Hi Austin :) Thank you for your input. I tried a few examples to compare the sine of the angle with its supplementary angle sine, and both sines are equal: http://s17.postimg.org/fi2qivfdr/angle.png Could you please share your examples? What did you enter? Our email is calc@mathlab.us Mathlab Apps, LLC March 18, 2015

(1) The inverse function for sin is arcsin. Touch and hold sin to enter arcsin. (2) The inverse function for cos is arccos. Touch and hold cos to enter arccos. (3) The inverse function for tan is arctan. Touch and hold tan to enter arctan. Look at the video how to use keyboard to enter arcsin, arccos, arctan etc.: http://youtu.be/ceiUrwa4WGI Very good, but takes some getting used to... It works extremely well and does what it is supposed to quickly, but the keys are sometimes a little bit of a challenge to find.

Mathlab Apps, LLC March 25, 2015

Quick Help: http://s12.postimg.org/t9ffg9z6l/3_K.png Look at 3 screenshots. First Screen: click on the icon with a question mark inside of the circle. Second Screen: you'll see the text of the Quick Help. Roll down to see the Third Screen with the Keyboard Map. Find the needed function and which button to push and hold. Also: http://help.mathlab.us Good aid to my calculus studies! Took me a little bit to figure out how to graph but it was worth it.

Mathlab Apps, LLC March 26, 2015

Look at the video (6'37"-7'30") how to graph: www.youtube.com/watch?v=doIYR6hUCpg Also look at the Chapter 4 "Graphing functions" of the User Manual: http://help.mathlab.us Yeah, it's good I would give this application a 5/5, exept for the fact that on a mobile with limited screen area it's hard to work with sometimes. Other than that it can do practically anything you need it to regarding math. Perfect in software design.

Mathlab Apps, LLC March 18, 2015

The app works for all android devices, including TABLETS also! www.amazon.com sells new android tablets from $39. Recently we have produced the special version of this app for the manufacturer of the huge android TV designed for schools. You may click on the button inside of the red circle to get more space http://s22.postimg.org/71ol2cept/Hide.png Useful & Practical Have been using the app in a precalculus class and it has become my favored calculator. It works very well and has no failed me yet (Great job guys!).

Mathlab Apps, LLC March 23, 2015

Our pleasure :) Very, very good. Only way i can see to improve it is a variable button, and a way to make scatter plots.

Mathlab Apps, LLC March 24, 2015

Scatter plots: http://s10.postimg.org/gowmwk0t5/image.png You can use many variables http://s3.postimg.org/or5cixgyb/variables.png Scroll the keyboard horizontally to see Latin and then Greek keyboards to type additional variables. Pinch the screen with 2 fingers to zoom out or zoom in. Moving your finger on the screen, you can move graphs. Really loved it The best calc available on play store.the only problem is it's not able to graph inverse trigonometric function (its understanding tan^-1 x as cotx).Please solve this

Mathlab Apps, LLC March 14, 2015

It counts all inverse trigonometric functions (arcsin, arccos, artanh etc.). Look at the video: www.youtube.com/watch?v=ceiUrwa4WGI Arctan is the inverse function for tan, so hold the button tan to choose arctan. Also, you can see 2 other options to choose there: cotangent, or arccotangent. Here is the User Manual: http://help.mathlab.us Mathlab Apps, LLC March 19, 2015

Hjelpesiden med instruksjoner og eksempler: http://help.mathlab.us Google-Robot har oversatt http://help.mathlab.us til norsk språk: http://translate.google.com/translate?hl=en&sl=en&tl=no&u=http%3A%2F%2Fhelp.mathlab.us%2F&sandbox=1 Mathlab Apps, LLC March 23, 2015

Please tell us more about your needs regarding mixed fractions. Probably, you need just to change Settings to get what you need. Our email is calc@mathlab.us Also try our Fraction calculator: https://play.google.com/store/apps/details?id=us.mathlab.android.frac Radians to Degrees? There's no button to change modes, which is extremely irritating, since I have the "Pro" version. I would've thought that they'd atleast think of adding a button to change from radians to degrees.

Mathlab Apps, LLC March 16, 2015

By default, the app counts in radians. For example, 45 it interprets as 45 radians. If you enter 45°, it interprets as 45°. You can switch between "Radian" and "Degree" using Settings: http://s24.postimg.org/936qf8ehh/D_R.png Mathlab Apps, LLC March 18, 2015

Hi Thythy :) We're glad you like our calculator! However, If you like it, why did you grade our calculator "3 stars" only instead of "5 stars"? The rating "3 stars" means "the app is ok, but not really good". Could you possibly consider changing your rating? Mathlab Apps, LLC March 23, 2015

Thank you for recommending the app for your students. Hope it might simplify your difficult work to teach. Thousands students sent us emails about how the app helped them to achieve As for all math-related courses and to make them to feel very confident in math. Just observing calculations when they type, students start to comprehend everything! # What's New

## Wabbitemu

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

## 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 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.

I'd love to hear your comments or suggestions. You can write me at the email address in the app. Thanks!

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.
