# Description

This application plots and analyzes mathematical function entered by the user.

It accepts input as a mathematical expression with a variety of operators, functions and constants.

The X and Y scales of the plot can be adjusted.

It resolves special intrests, such as:

- Extreme points (estimated)

- Roots (some exact, some estimated)

- Y axis intersection point (exact)

- Horizontal asymptotes

- Vertical asymptotes

These will be marked on the graph and shown as text below it.

And, should you allow it and ask it for the derivative, it can go online and download the derivative from the internet.

The full available operators, functions and constants list can be found in the application itself.

Supports: English, Hebrew. Note that Android devices with version 2.1 and lower can't install the current version, only an old one (which has no Hebrew)

Poor input My Android keyboard does not seem to have a '^'. This means I cannot raise anything to a power, rendering this app useless. Needs a custom keyboard in the future.

A Google User

Great The equations have to be written properly, works well, would be great if it could zoom, pan, and even plot points ;)

A Google User

Great app! Very useful Not only it displays the function graph but also the roots, asymptotes and derivatives, and allows to automatically graph the derivative. For this app to be just perfect for any math student it should allow to zoom in and out the graph, and maybe include a numeric/math keyboard that makes equation writing easier (since the regular android keyboard can be a bit tricky).

User reviews

Review Very Good app to use. Being a student of physics i find it really helpful

Asymptotes Does not give slant asymptotes, but great app.

Cuts it very well Very "simple" and extremely easy to work with.

FEATURES

Calculate any formula you want and show them in a 2d or 3d plot. The natural display shows fractions, roots and exponents as you would expect it from mathematics.

In a few seconds you derivate or integrate your desired function, calculate the zero points of your function und show them in the function plot. See all maxima, minima or inflection points in one view.

The easy way of use allows you to solve linear equations in just a moment. Or transform your mathematical, physical or chemical equation to any unknown variable.

You often needs to calculate with binary, octal or hexadecimal number systems? No problem! You can mix them together in one calculation even by using decimal digits. But that's not enough! You can also calculate with any other number system with base 2 to 18.

From time to time you may need to convert units to another one, like Celsius to Fahrenheit, miles to kilometre, inches to foot and so on.

You will also be able to calculate with vectors, matrices and determinants.

All this features are combined in this app and will make your mathematical life a lot easier.

Examples of possible functions :

f(x) = 5x+3

f(x) = 3x^2 (equivalent to 3x²)

f(x) = 4cos(π-x)

f(x) = tan(cos(x))

f(x) = ln(x+10)

f(x) = exp(-3x) (exp is exponential function)

f(x) = xsin(x) - 6/x

## Maxima on Android

Maxima, a full featured computer algebra system, now runs on your Android mobile devices. Maxima, and its predecessor Macsyma is one of the most long-established software in the world, back in 1960s at MIT LCS and Project Mac. You can perform many many math operations such as integration, differentiation, matrix operations, rational numbers, symbolic treatment of constants such as pi, e, euler's gamma, symbolic and numerical treatment of special functions such as sin(x), cos(x), log(x), exp(x), zeta(s), and many more.

Maxima on Android is a port of Maxima on the Android operating system. Thanks to Sylvain Ageneau' effort on porting Embeddable Common Lisp to the Android OS, the latest Maxima code runs nicely on ECL on Android with very small changes to the source code.

Maxima on Android is a combination of many open source software: ECL on Android, MathJax, and Maxima itself. I wrote roughly a thousand lines of Java code and a hundred lines of HTML including Javascript code.

The installation of the software requires total of 90MB on the storage. 30MB needs to be installed on the internal storage. The rest of 60MB can be installed either on the external or the internal storage. The first run of the apk will ask you where you want the 60MB to be installed.

Then you can enjoy Maxima / Macsyma on your mobile phone or tablet based on Android OS.
