# Casio Calculator CLASSPAD 330 PLUS

### Functional Upgrades for Greater Convenience as an Education Tool

#### Greater Expandability

^{*}

Projecting graphs and equations on the projector screen facilitates both learning and teaching.

*For information on supported models, refer to the following URL: http://edu.casio.com/

#### Greater Usability

Data transfer between a calculator and PC requires no special software and resembles use of a USB memory device. The Screen Receiver function makes possible screen captures and real-time display of calculator screens.

#### Higher Calculation Speed

The processor enables fast display of even 3D graphs and other graphic renderings.

#### Improved Environmental Performance

The use of rechargeable batteries reduces used battery disposal and helps reduce environmental impact.

### User-friendly Interface

#### Pen Touch Operation

Intuitive stylus operation for entry of values and expressions, selection of menu commands, drag-and-drop copying of values and expressions, and much more. A large 160 × 240-dot LCD simplifies operation and displays more data per screen.

#### Natural Textbook Input and Output

Fractions, powers, and square roots, as well as high-level mathematical expressions such as log, Σ, ∫, d/dx, lim, matrices, F (Fourier transforms), and L (Laplace transforms) can be entered and displayed just as they appear in your textbook. An on-screen soft keyboard helps to simplify entry of complex expressions.

### ClassPad 330 PLUS Built-in Applications for Version 3.1

#### Advanced CAS (Computer Algebra System)

Base-n capabilities have been added for general-purpose numerical and mathematical calculations. Natural input/output mathematical functions have been expanded to include F (Fourier transforms), L (Laplace transforms), δ, Γ, H, and more.

#### Differential Equation Graph Application

The solution set of a differential equation can be represented graphically as a vector field, and solution curves can be drawn by providing initial conditions for the equation. First, second, and n-th order differential equations are supported.

#### Financial Application

This ClassPad 330 PLUS application provides you with a total of 15 different financial calculations, including simple/compound interest, cash flow, amortization, depreciation, bond calculation, operating/financial leverage, and more.

#### E-ConEA200

E-ConEA200 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.

### Spreadsheet Application

Collected data can be organized and tabulated for analysis after statistical graphing is complete. Spreadsheet data also can be used in table calculations. In addition, ClassPad 330 PLUS supports the following functions: search, sort, data import from and export to lists, matrices, and variables, CellIf, and Histogram/Box-whisker graphing.

### Geometry Application

A collection of versatile Geometric Graphing Functions enables efficient drawing and analysis of geometric figures.

#### Geometric Graphing

Students can learn the general theorems by drawing figures and can confirm that a theorem still holds true even when the form of the triangle is altered.

#### Geometric Graphing Using Drag & Drop

Dropping a geometric figure into the Main application window will produce the numerical data for the figure. Conversely, dropping numerical data into the Geometry window will produce the applicable figure.

#### Animation

An Animation function provides the means to move geometric figures drawn on the screen. You can even plot the locus for a particular point of the animation. The screenshot shows an example where Point D is plotted as the locus for Point E moving on Line AB.

#### Enhanced Geometric Functions

ClassPad 330 PLUS supports drawing of conics using a focus, as well as graphing of polar equations and parametric equations. Enhanced labeling capabilities let you display attached angles, measurement-based calculation results, and more.

### eActivity Application

An eActivity is like a digital worksheet that can be created and worked with on the ClassPad 330 PLUS. All of the powerful features and capabilities of the ClassPad 330 PLUS can be incorporated into an eActivity. In addition to being able to perform the same calculations as the Main application, an eActivity will accept text entry, just like a word processor. Graphs, as well as Geometry and Spreadsheet data, can be stored in an eActivity file.

### 3D Graph Application

The 3D Graph application lets you draw rectangular coordinate graphs (z = f (x, y)) and parametric function graphs (xst = f (s, t), yst = f (s, t), zst = f (s, t)). You can split the display screen between a 3D Graph Editor window and 3D Graph window, or enlarge the 3D Graph window to view a larger graph.
