Q. How do I view the Step-by-Step screen for a problem?
A. First enter the problem into the calculator and hit enter to see the result. Then click on the result. Make sure you are clicking on the result and not its input, as clicking on its input will paste the input into the current entry field. Also, Step-by-Step must be enabled in the settings when the result is calculated. By default Step-by-Step is enabled.
If you are not completely satisfied with your purchase and you email me at email@example.com within 14 days of your purchase, I will give you a refund. Please include your order number in the email. (Google play only gives you 15 minutes to automatically get a refund, I think this is too short). You can only request a refund once.

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!

You can also solve differential equations and plot graphs of your choice
Now, do your homework easily when the app :
-- Shows all the steps of differentiation and integration
-- Supports a wide range of functions (trigonometric, polynomial, logarithmic / a combination of them)
-- Draws a graph of any mathematical function
-- Allows you to solve differential equations with initial value problems.
-- Allows you to view the raw data of every computation
-- Has pinch-to-zoom feature so that you can analyze your solutions well
-- Uses multicolored graph plots so that you can compare the solutions of differential equations
For feedback and suggestions, send an email to firstname.lastname@example.org. Note that the app is ad-based which is not shown in the screenshots for clarity.

touchGrapher is a graphing calculator, a mathematical tool, which lets you draw graphs of functions of one variable on a plane. Simple navigation and possibility of managing every function after it has been drawn provide for usefulness in many applications and helps you save time in many situations.
In the current release the following are available to create your own functions: basic arithmetic operations, trigonometric functions, cyclometric functions, hiperbolic functions, logarithms of any base, roots of any base and more. The appearance of every function can be adjusted before or after it has been drawn, you can also set the order of the functions on the plane(e.g so no function covers the one you want to be on top).
Additional functionalities in current release include:
- numerical integration
- finding zeros, local extrema(maxima and minima), intersection points
- generating a function from a discrete set of points using:
- linear regression
- exponential regression
- polynomial interpolation
**Warning this is an alpha version, the app is incomplete and no number given by it should be considered correct until the app is actually release, you have been warned**
**This project has been orphaned. No one is currently developing it as the project was too large for one programmer to manage.**
Ever hated the fact that good graphing calculators are so expensive. When you have to have a good calculator but you don't want to pay $100, you can't do the work properly, and you can't get it done without hours of work, or at least an internet connection. Well now there is Mathulator.
It makes no sense that you have a phone or a tablet that is capable of doing everything that expensive calculator can do but still have to get it anyway. Not anymore. Mathulator aims to be the ultimate calculator, capable of doing anything those amazing graphing calculators can do, in color, with a touchscreen, and in your pocket wherever you are.
For those of you who are familiar with those fancy-shmancy it will still fit right in. The syntax and input is the same format as most new Texas Instruments calculators with only a few exceptions.
or if you want to take a look at the source check out
As of now there is a lot of Mathulator that doesn't work. Even more of it hasn't been written yet. There is very little left to do before the app is taken into beta. The last of it being an entire code cleanup that will fix hundreds of things that don't work quite properly yet. The reason why some things are being put out there broken is to see how issues come up most often to find the best ways. Other things are broken simply because the code that actually does the math is what need the overhaul the most so we will fix all the math code at once. So if there is a function that isn't working or an error where there shouldn't be during evaluation it will probably stay that way until beta. However if there is a problem with the interface we will try to fix it by the next update.

It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function, and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function.
Eg f (x) = x ^ 2 + x, after insertion, type f '(x) to display the graph of the derivative.
To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";".
