•To pass over directly from theory to practice, there are more than 60 math problems with solutions.


Recommended Usage:
•Parallel in the lesson:
One main problem, why students don´t understand the graphing calculator is, that they get wrong results
and don´t know, what they have to enter.
•Discharge for the teacher:
If every student receive instantly the right solution, there will be no more wasted time to solve problems

Not yet convinced? Here's the detailed description:
•Every topic shows a detailed instruction through Screenshots of the original graphing calculator how to solve the exercise. You only have to slide to get the next Screenshot which looks similar with your calculator!
•To ”become warm” you have the possibility to insert a sample function in your calculator which is used in the App. The App shows an example for every topic (e. g. a registered function in the GRAPH-Menu). •After that, press the first button of the particular key combination on the graphing calculator. Then slide once again to get the next Screenshot. These will look like the display of your calculator, if you did everything right. The App contains for each step a picture to make it easier to solve the exercise.
Of course there is an exact key sequence for every topic which uses images of the original buttons!

•The app is also useful for preparing your examination, because you often don't remember all instructions of the calculator.

•Your teacher will be grateful as well, because he doesn't have to walk around the classroom until everyone's calculator shows the right solution. You only have to take a look at the app and know how to do !

•The app contains the following topics:
Differential Calculus, Integral Calculus, Solve Equations, Matrices, Basic Knowledge in GRAPH-Menu, how to fix all kinds of errors, the calculator might show (Syntax Error, Condition Error…) and:

•CAS (Computer Algebra System)
The App describes the CAS, how to install it on your calculator ( then you can install games on the same way) and the use of it. With a CAS you are able to calculate the derivative or antiderivative (not only graphically) and much more.
For example you enter: 5x^3 + 2x in your calculator and the derivation of 15x^2 will be calculated automatically. This is very useful in case of checking your own results. (An example is included in the Store as a Screenshot)
