Features
Userfriendly Interface
Pen Touch Operation
Intuitive stylus operation for entry of values and expressions, selection of menu commands, draganddrop copying of values and expressions, and much more. A big 160 × 240dot LCD simplifies operation and shows more data per screen.
Natural Textbook Input and Output
Fractions, powers, and square roots, as well as highlevel 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 onscreen soft keyboard helps to simplify entry of complex expressions.
ClassPad 330 Builtin Applications
Advanced CAS (Computer Algebra System)
Base n capabilities have been added for generalpurpose 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 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 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.
Spreadsheet Application
Improved 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 adds the following functions: search, sort, data import from and export to lists, matrices, and variables, CellIf, and Histogram/Boxwhisker graphing.
Geometry Application
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.
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.
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.
Enhanced Geometric Functions
ClassPad 330 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, measurementbased calculation results, and more
eActivity Application
An eActivity is like a digital worksheet that can be created and worked with on the ClassPad 330. All of the powerful features and capabilities of the ClassPad 330 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 also 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.
