Function Derivatives, offline

This is an app for student and pupil.
You can solve the derivatives of nearly every function, homework, exercises und LEARN how to solve.
This app demonstrate the solution of each exercise step by step.
You can enter your mathematik homework or generate automatically an exercise and learn the solution way.
The main aim of this app is to show you HOW to SOLVE an exercise.In this app you can learn to solve the following function (Mathmatics) types:Polynom, trigonometric functions (Sinus, Cosinus, Tangens, Cotangens, etc.), logarithmic functions (ln, log), exponential functions (e-Function), Hyperbolic functions, (Sinus hyperbolikus, etc.), rational functions.
This App computes the derivations of all function types.
You can enter your own exercise or homework or generate a function automaticaly.
Thanks for positive feedback.I wish you success!
