Use the graph apps to visualize and analyze the graphs for different types of functions.

### Function-App

Using the Function App to properties of various functions of an independent variable and their corresponding graph can be investigated in detail:

 In the symbol -view the function terms are entered and the colors for the graph definded. The test functions are activated by tick box. In the Plot -view the corresponding graphs are displayed and can be zoomed with the + and - keys. An analysis of the graphs can be done on different ways, for example, zeros, gradient, extrema intersection (s) directed graphs area between two graphs or graph and x-axis. In the Num -view the corresponding value ​​tables are displayed. With a flick of the finger on the multi-touch display can be comfortably scroll through the tables of values​​. Using the "Zoom" function can be "refined" arbitrarily the value tables.

With the help of this application you can draw graphs in the x / y plane. For definition either equations or inequalities can be used.

 In the symbol -view the defining equations are entered and the colors for the graphcan be set. The test functions are activated by tick box. In the Plot -view the corresponding graphs are displayed. By touching the multi-touch display, the graph can be adjusted arbitrarily. A zoom function is available via the + and - key . The Num -view shows which pairs of points of the x / y-plane corresponds to the graph (true / true). With a flick of the finger on the multi-touch display can be comfortably scroll through the tables of values​​. Using the "Zoom" function can be "refined" arbitrarily the value tables.

### Parameter-App

Using the App Parameter display graphs that are defined by means of parametric representation.

 In the symbol -view, the x / y coordinates can be defined as a function of the parameter T and can be set colors for the graph. The test function can be activated by tick box. In the Plot -view the graph is displayed. By touching the multi-touch displays, the graph can be adjusted arbitrarily. A zoom function is available via the + and - keys . In the Num -view for every parameter value T to display the corresponding x / y coordinates. With a flick of the finger on the multi-touch display can be comfortably scroll through the table of values. Using the "Zoom" function, the value table are "refined" arbitrary.

### Polar-App

With the help of Polar App you can display graphs that are defined by polar representation.

 In the symbol -view the term for the radius as a function of the angle is defined and you can set the color for the graph. The test function is activated by selecting the hook. In the Plot-view its graph is displayed. By touching the multi-touch display the graph can be adjusted as desired. A zoom function is available via the + and - buttons. In the Num -view, the polar coordinates are displayed. With a flick of the finger on the multi-touch display you can comfortably scroll through the table of values. Using the "Zoom" function, the value table are "refined" arbitrary.

### Sequence-App

With the Sequence App you have the possibility to process a variety of growth processes or (transcendental) equations, such as x = cos x interactive. The consequences can be explicitly or recursively defined.

 In the symbol -view the desired sequences are defined and activated by the tick box. In the above example, the logistic function with parameter 2.75 and the start value of 0.1 is used as an iterator. In the Plot -view, the iterations are illustrated graphically using a web diagram. By touching the multi-touch displays, the graph can be adjusted arbitrarily. A zoom function is available via the + and - keys . In the Num -view the results of each iteration are displayed. With a flick of the finger on the multi-touch display can be comfortably scroll through the table of values. Using the "Zoom" function, the value table are "refined" arbitrary.
