CASIO Graph Calculator Manual

CASIO Graph Calculator Manual

Marco Wenisch

• This app shows all important functions of the graphing calculator CASIO fx-9860GII, which are very useful for final secondary-school examinations (also suited for fx-9860G and CFX-9850G).
• The apps shows exactly which buttons you have to press on your calculator for every topic.
• Through the support of CASIO the original illustrations can be used.
• You can swipe through screenshots of the original graphing calculator which show every step you have to do.
• There are helpful descriptions in the app which give some additional info.

6 Reasons to buy this app:
1. 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

Multi Fit Graph Calculator

Multi Fit Graph Calculator

Amran AlQasmi

iCurve Fitter & iMulti Fitter, are of the best graph applications available in the App Store, yet easy to use. they are handy tools essential for doctors, engineers, students and laboratories. Used to derive the mathematical equation that fits a set or multiple sets of experimental data points, at any required degree. it uses advanced polynomial Interpolation method to plot those data points and draw the derived equation’s curve. Just enter your experimental readings in pairs of (x, y), and the app will do the rest for you, and represents the graphical output instantly on a Cartesian plane. You can always manipulate the graph interactively (zooming in/out, scrolling and tracking). so you can determine the value of (y) for any given value of (x), plus the slope of the curve at that specific point. also you can get the precise numbers using a dedicated Solver UI. and now you can calculate & visualize area under curve for a given interval. you always can get the derived equations and numerical results in a formatted sheet that can be exported or shared. Minima, maxima & root points are also calculated and represented automatically.

► Features:
- Easy Data Points entry form.
- Specialized numeric & function keyboards.
- Controlling graph look & behavior.
- Controlling properties of Pen, Text, Color for both curves & graph.
- Automatic axes Scaling.
- Zoom in/out, scrolling & Tracking.
- Reset Graph, Origin.
- Graph lock.
- Customizable Degree of Interpolation with direct curve redraw.
- Exportable calculations Sheet.
- Interactively & numerically entered limits specification.

Graphulator is a numerical graphing calculator for 2 or 3 variable equations. Plot both functions and non-functions. Includes data output! Now includes numerical calculus.

Scientific calculator.
Trigonometry.
Logarithms.
Absolute values.
Scientific notation.
Basic Calculator.
Function calculator.
Two variable calculator.
Three variable calculator.
Numerical analysis.

Drag grid or use controls to move or change the scale.
Drag three variable grid to rotate.

Graphulator can miss non-functions 1/50 the grid scale. The user can adjust the accuracy or change the grid scale including adjusting the width and height independently.

Graphulator boasts being the only calculator which can perform calculus on non-functions numerically (equations which cannot be reduced to a function). It should be noted that these derivatives differ from standard calculus.

Graphulator boasts being the only numerical calculator which can plot three variable non-functions.
(Equations of the form f(xyz) = f(xyz)).
