Graph

畫出你的函數在一個簡單直觀的方式。

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.

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.

Developed by Amadeus Gebauer.
