Functions Studio

执行函数y = f（x）的实变量的，真实的研究

Study Functions ADS performs the complete study of a real function of real variable y = f (x).

All basic functions are supported (sin, cos, sinh, etc.)

The app is drawing for devices with a large screen, mainly tablets with a screen of at least 8 inches, but I also use it with my J7 with a screen of 5 inches.

This application isn't free, so it haven't Advertising. If you want the free version with Advertising, download "Functions Studio ADS".

To insert new functions (the functions available are in the Help section?), From the Functions menu select Insert Function, enter the function in the box above the graph, when you click on "Done" the function will be validated. If you see the function with its derivatives on the right-hand blackboard, you have entered the function correctly, otherwise you will see an error message.

The functions can be saved in a database to be recalled at will from the Functions menu.

From the analysis menu you can do the various stages of the study one by one.

1) Field of existence

2) Intersections with the axes

3) Vertical asymptotes and discontinuities

4) Horizontal and oblique asymptotes

5) First derivative study

6) Second derivative study

If you prefer from the Functions menu you can select Complete Study and you will find on the right hand blackboard all the results related to the sections described above.

The colors of the various elements of the chart and the size of the characters on the right hand side can be customized as desired by clicking on Settings. If you choose colors that do not satisfy you with a click you can restore the colors and the font size by default.

The app is thought to work only with the larger side of your device as a base (landscape).

Good study.
