Casio FX-CG20 Graphic Calculator - Color Screen

A next-generation color model that carries on the tradition of innovation in CASIO graphic scientific calculators!

Vivid colors and smooth fonts for easily readable graphs and formulas!

Create function graphs overlaid on color images!

Automatically links colors of values on the spreadsheet screen with colors used in graphs!

The color display, with more than 65,000 colors (384 x 216 pixels), is capable of rendering in crisp, clear colors line, pie, and bar graphs as well as minute details such as graph gridlines and coordinate axis labels and coordinate values displayed during tracing. In addition, the display features a high-quality LCD panel that delivers excellent visibility and low power consumption and enables long run time of approximately 140 hours from four AAA alkaline batteries.

The fx-CG20 comes with smooth, easy-to-read fonts with character definition of up to 18 x 24 dots that clearly display mathematical equations and other text. Furthermore, the calculator automatically color codes brackets to facilitate the input of complex equations with multiple brackets and improve equation viewability.

The fx-CG20 features the Color Link function, which automatically links colors specified on the spreadsheet screen with colors used in graphs to support learning of functions by enabling visual confirmation of changes in values or trends.

The calculator comes pre-loaded with visuals such as a single image (still image) of the curve of an arched bridge and multiple images (sequential images) of the rotation of windmill blades. The use of real-life visuals as background images for functions such as the drawing of graphs overlaid on color images makes mathematics learning a more visually familiar experience.

Students can create a wide variety of graphs over real-life visual backgrounds.

The use of real-life visuals makes it fun and easy to study various aspects of geometry, including the drawing of shapes, movement, and similarity relations.

Students can search for and plot curves found in nature and their surroundings. Analysis of the plotted data deepens understanding of the function.

Plotted G3P files can be used in Graphing , Geometry , Picture Plot , and eActivity.

Plotted G3B files can be used in Picture Plot.

CASIO's original "Natural Expression Input Display" and "Natural Expression Output Display" make it possible to display fractions, exponents, logarithms, powers, and square roots just as they are written in the textbook. The result is enhanced student comprehension and improved math class efficiency.

Input expressions and arithmetic operations as they appear in written form.

Calculation results appear in the same format as they are written.

Perform operations on vectors and calculate the inner product and outer product.

Verify the integral value in real time while freely moving the interval using the cursor key.

Calculate the values of integrals and the area enclosed by two graphs.
Not only arbitrary points, but also points of intersectionand the points where Y=0 can be selected in the intervalof integration.

Population standard deviationand population variance commands have been added.

Use shuffling or random selection to select data from an existing list and prepare new list data. Use the new list data to verify various statistical patterns

This function clearly indicates the calculationorder when the calculation priority sequence is ambiguous.

The calculation result display has been improvedfor simultaneous equations with an infinite number of solutions.

fx-CG20 calculator come with the same eActivity capabilities that originally appeared on the ClassPad 330. Now teachers as well as students can create their own problems and study materials. Students get the opportunity to learn at their own pace for more efficient study both at school and at home. eActivity is a great motivator for learning and understanding.

Normal distribution, Student's t-distribution, and other often-used statistical calculations are provided in function format for easier practical application.

Store a list of values in memory for use when performing function and statistical calculations, when drawing graphs, or when generating tables of numeric values.

Perform tests, confidence interval, probability distribution, and other calculations and graphing.

New support for graphing the inequality of an x=Constant graph and x=f (y) graph allows study of the area for which the x-range is defined.

• Depreciation
• Bond calculation
• Simple interest
• Compound interest
• Investment appraisal (cash flow)
• Amortization
• Interest rate conversion (annual percentage rate and effective interest rate)
• Cost, selling price, or margin
• Day or date calculations

A multi-function spreadsheet with built-in graphing capabilities is a valuable tool for table calculation lesson exercises.

E-CON2 provides total control over the optional EA-200 Data Analyzer.
It makes it possible to measure changes in temperature, sound, or speed using the EA-200 without any troublesome settings or program input.
