Keys are too small, some are unreadable. Unable to get the simplest graph drawn. I think the developer can fix this and I hope he/she does.

A Google User

Looks very nice, and seems to work well, but I really need a graph to plot polar functions.

A Google User

Great app, but very difficult to write a function... please little more friendly user app

A Google User

wish if the buttons were bigger otherwise the app really helps in drawing funcions... thanxxx

A Google User

Can not use calc keyboard. Is tiny and unreadable.

A Google User

The calculator is not usable. The buttons are not big enough to fit the text. Deleted until it is fixed.

Conceptul este bun, aplicaţia ar putea fi foarte utilă. Cu toate acestea, butoanele sunt prea mici pentru a putea fi utilizat, cel putin pe Galaxy S.

It supports normal mathematical operators and some of the more common mathematical functions (trigonometric, ln, exp). Any function can have up to 10 inputs and 10 outputs. Currently does not handle imaginary numbers.

Listen Read Device Only Added Installed Graph provides you a powerful function graphing application. You will like to use the app because of the intuitive handling and the intelligent structure of the app. Although the app has got diverse possibilities, the usability has never been left behind. See also at the adfree professional version which is provided with faster updates and more functions. The features:

- Support (almost) every type of function

- Graphic representation of the equations

- Possibility of using many parameters (only in the professional version)

- Draw the first or second derivative of an equation

- Draw the integral of an equation

- Calculation of roots, local extrema, saddle points and inflection points* (only in the professional version)

- Draw the coordinates to an specific x-Position (only in the professional version)

- Draw the tangent to an specific x-Position (only in the professional version)

- Draw the normal to an specific x-Position (only in the professional version)

- Calculate the definite integral of any equation

- Manage your graphs in different sessions

- up to two different equations (limitless amounts in the professional version)

- Export your graph as PNG-file

- Use intuitive multitouch gestures to zoom in your graph plot

In schools, universities or at work: The graphic representation of Equations is useful in many kinds of your daily routine.

The app supports the following function types:

- polynomial function, rational function

- Sinus, Cosinus, Tangens

- Arcussinus, Arcuscosinus, Arcustangens

- Sinus hyperbolicus, Cosinus hyperbolicus, Tangens hyperbolicus

- Arcussinus hyperbolicus, Arcuscosinus hyperbolicus, Arcustangens hyperbolicus

- Logarithm, natural logarithm, Logarithm to any base

- Squareroot, cubicroot, root to any exponent

- Absolute, Signum (only in the professional version)

- Derivative (only in the professional version)

- Round, Ceil, Floor (only in the professional version)

In the professional version it is possible to define up to 13 parameters and you can explore the graphs (coordinates, tangent, normal).

* We are testing this feature at the moment. The points were calculated numerically. That's why it is possible that not all points are found, especially with non continuously differentiable functions.

Are there any open questions? Send us an E-Mail: cassiopeia.applications@gmail.com

Why does this application need the permissions:

Internetconnection: To support the development of this app, I added advertisements to the app.

Write on external storage: To export the graphs as an PNG-file we need to write on the external storage.

In addition to the classic functions of a scientific calculator this application is also able to calculate complex mathematical expressions and to design, simplify, solve and find derivatives up to N order.

Sci Calculus can be used also to convert numeric base (hex<->bin<->dec).

The application also uses (in addition to normal "OK" button) the accelerometer to show the result on the screen (just shake the phone).

Listen Read Device Only Added Installed ## Scientific Calculator Plus

CYZ SOFT

1

Listen Read Device Only Added Installed Scientific Calculator Plus is a powerful mathematical tool to do mathematical analysis and evaluate complicated mathematical expressions similar to Matlab. More than Matlab, it has a mathematical equation(s) solver which helps user to solve mathematical problems. It supports complex number, matrix, (higher level) integration, 2D, polar and 3D chart, string, programming (using a easy-to-use language called MFP) and unit conversion. It can run in both Android phones and tablets, PC or MAC with JAVA installed. Scientific Calculator Plus for Android includes a Scientific Calculator Plus for PC and Mac. User can connect mobile device to any PC or MAC via a USB cable, copy SDcard\AnMath\ folder to his/her own directory and launch the JMathCmd.jar in it. User can also download standalone Scientific Calculator Plus for JAVA (and for .Net) and docs at our website

This calculator has provided more than 100 diffused functions covering trigonometric calculation, complex number, matrix, integration, string and chart plotting. It is also able to handle mathematical operators like plus, division, power, percent, etc. And these operators fully support matrix and complex numbers. Thus user is able to evaluate complicated expressions, which are either not supported or hard to input in most traditional calculators. Moreover, the calculator is actually based on an easy-to-use programming language called MFP. Users can develop their own functions using this tool by a PC editor, store them in mobile SD-card and use them in calculator or command line. As a programmable tool, it can do everything.

The calculator can also think for user. It is able to solve unknown variables from complicated expressions and show the result to user. To calculate result of an expression, user input an expression like 3 + log(4.1 / avg(1,5,-3)). To solve unknown variables, user input single expression like log(x) - 7== 3, or a group of expressions like

y1/3+y2==7

y2/2-y3+y1==9

y3+y1+y2==2.4

. Then simply press start button, user will see value of 3 + log(4.1 / avg(1,5,-3)) or solved x or y1, y2 and y3 value.

This calculator has two basic user interfaces: smart calculator interface and command line interface. In the smart calculator interface, user is able to define variables, solve equation(s) and input expression(s) from historical records, using keyboard or clicking function buttons. Function buttons are configurable so that user is able to define his/her input keypads to input user-defined functions quickly.

User can also input expressions and plot 2D, polar or 3D charts in smart calculator. The number of unknown variables and variable name determine whether 2D, polar or 3D chart is plotted. After chart is plotted, smart calculator will show chart snapshot in the output box and history record. User can review the chart by simply clicking the chart snapshot

In the command-line interface (which works like Matlab), user uses keyboard to input expressions and sees the print output (which is not shown in the calculator interface) and return value. Command-line interface is best tool for developers to output intermediate results in their functions.

In order to help user input and evaluate (higher level) integration and plot charts, this calculator includes built-in integration and chart-plotting utilities. User no longer needs to type long and complicated expressions. Instead, by simply filling the text fields and pressing buttons, user will see the results or the charts. All the charts are automatically saved in SD-card which can be viewed and managed by file manager of the calculator later on.

Like Matlab, the calculator also provides a small program editor which gives developers much convenience to build their own functions. Nevertheless, they can also user a PC editor to do this job and save the program files in SD-card for future use.

Thanks to its smart layout engine the user interface stays always clear independently of different screen sizes. Usage is very similar compared to a usual hardware calculator. If present feel free to use your physical keyboard. Haptic and visual feedback can be toggled in the menu. The calculator offers the following features and functions:

- basic arithmetic operations in line with BODMAS rule and with up to ten brackets

- fractional arithmetic

- root

- trigonometric and hyperbolic as well as their inverse functions (degree, grad, radian)

- logarithmic and exponential functions

- binary, octal and hexadecimal calculations

- sexagesimal conversions

- more than 40 constants of physics, math and chemistry

- memory functions
