Studio ADS functions carries out the comprehensive study of a real function of a real variable y = f (x).
all the basic functions are supported (sin, cos, sinh, etc.)
The app is designed for devices with a large screen, mainly tablet with a minimum of 8-inch screen, but I use it even with my J7 with a screen size of 5 inches.
This application is free and will offer you the ad in full screen when you click on the various functions available, if you want to remove advertisements purchased the application:
"Studio functions".
To add new functions (functions are available in the Help section?), You have the Functions menu, select Key, enter the function that, when you click in the box above the graph on "Done" function will be validated. If you see on the blackboard on the right function with its derivatives have entered the function well otherwise you will see an error message.
The functions can be saved in a database to be called up at will from the Functions menu.
From the analysis menu, you can do one by one the various phases of the study.
1) Field of existence
2) Intersections with the axes
3) and vertical discontinuity Asymptotes
4) horizontal and oblique Asymptotes
5) Study the first derivative
6) Study the second derivative

If you prefer you can select from the menu functions Complete Studio and you are on the board right all the results of the previously described sections.
The colors of the various elements of the graph and the size of the board to the right characters are customizable at will by clicking on Settings. If you choose colors that do not meet you with a click, you can put the colors and the size of the default font.
The app is designed to work only with the largest side of your device as a base (landscape).
Good study.
