Includes 42 topics for high school and college(all you need) 2. Easy key-press-sequences to solve math problems fast 3. The app includes more than 300 screenshots (one screenshot for each step of each topic) 4. An example for every topic to learn new stuff 5. Infoboxes for more detailed explanations 6. More than 60 math problems and a quiz to practice your skills 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-press-sequence 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. The key-press-sequence contains images of the original buttons, that you can find the keys very fast on your calculator! • 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. • The app contains the following topics: DIFFERENTIAL CALCULUS • Zeros of a Function • Y-Intercept • Calculate Tangent • Calculate Normal • Intersection of two Functions • Maxima • Minima • Draw Derivation • Inflection Points • Y-Calculation • X-Calculation • Regression • Find the Equation of a Curve INTEGRAL CALCULUS • Integral in RUN-Menu • Integral in GRAPH-Menu • Area between two Functions • Find Area with Absolute Value SOLVE EQUATIONS • Simultaneous • Polynomial • Solve Equations MATRICES • Save Matrix • Put into Row Echelon Form • Solve Matrix • Transpose of a Matrix • Inversion of a Matrix • Identity Matrix BASIC KNOWLEDGE • MENU Settings • Insert Functions with Parameter • Select/ deselect Functions HOW TO FIX... ? • Syntax ERROR • Condition ERROR • Range ERROR • Argument ERROR • Stack ERROR • Memory ERROR CAS • What's that? • Installation Instructions • Differentiation • Integration • Expand an Expression • Simplification • Solve Equations exactly MATH PROBLEMS • Practice with over 60 math problems and solutions • You can practice math problems of a single topic (e.g. Zeros of a Function) or random math problems of Differential Calculus for example. • As an alternative the app shows you mixed math problems of all topics. ## Key features - Step-by-step button press instructions - Original calculator illustrations - Over 300 screenshots - Examples for every topic - Infoboxes for detailed explanations - 42 high school and college math topics - Practice quiz and math problems ## Recent user reviews (9 of 9) All indexed reviews: https://appshunter.io/ios/app/casio-graph-calculator-manual/id867458554/reviews.md ### 1/5 — Mauvais produit *2024-10-14* Ceci n’est pas une calculatrice ne payez pas ! ### 1/5 — Not worth it . *2023-07-04* It’s does not show all the details . ### 1/5 — 退钱 *2019-11-07* 退钱 ### 4/5 — Cascorrection *2017-11-05* There was an issue with CAS. After getting in contact with the help desk, the issue was solved ASAP. The app has been a great help in learning about the Casio 9860II graphic. The manual is helpful, and the help desk is responsive. L.B.(tech) ### 1/5 — App crashes when opening *2017-04-24* The moment you open the app there's a pop-up with a code error and the app closes. How did this make its way into the app store? **Developer response:** Hey, thanks for your review. This error pop-up appeared when the app was opend on an iPad used in landscape mode.

Nach kurzem Überlegen erscheint die Fehlermeldung "Error #404 - uncaught error, null is not an object ....", die man nicht über "ok" wegklicken, sondern nur nach oben oder unten schieben kann, bis die App abstürzt. **Developer response:** Nutzen Sie ein iPad? Uns ist bekannt, dass dieser Fehler im Landscape Mode auftreten kann. Versuchen Sie die App zu starten, indem Sie Ihr iPad so halten, dass der Home Button unten ist. Eigentlich sollte dieses jedoch mit der App-Version 2.2.0 behoben sein. Wir würden uns über Feedback freuen! ### 1/5 — This does not work *2015-10-28* How do I get my money back please? ## Frequently asked questions about CASIO Graph Calculator Manual ### What CASIO graphing calculators does the CASIO Graph Calculator Manual support?
