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.

## Graph It!

FEMA

1

GraphIt is a utility that is used to display on a Cartesian plane any mathematical function, which can be f(x)=2, f(x)=2*x, f(x)=sin(x) ecc... The management function is entrusted to you: you can add more or modify existing ones.

The integration of functions is facilitated by self-completion of statements, also expressions of the interpreter is very flexible and allows the inclusion of any function: even the most complex are recognized and interpreted correctly.

The main functions recognized are: abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), avg(x1,x2,...,xN), ceil(x), combin(x,y), cos(x), cosh(x), e(), exp(x), fact(x), floor(x), lg(x), ln(x), log(x,y), max(x1,x2,...,mN), min(x1,x2,...,xN), mod(x,y), pi(), pow(x,y), rand(), sign(x), sin(x), sinh(x), sqrt(x), sum(x1,x2,...,xN), tan(x), tanh(x), toDeg(x), toRad(x).

The graph allows an accurate view of the trend of function at any point in the plane. You can zoom and pan through the classical gestures.

There is also a tool which can calculate the value of the functions included, given the value of x (via a number or expression).

## 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.

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
