Vivid Color Display and Touch Panel for Superb Usability | Horizontal Screen View - Display long formulas on a single line | Formulas, graphs, and other graphics are sharp and clear - The display has resolution of 320 x 528 pixels (more than 65,000 colors), 4.4 times higher than ClassPad 330 PLUS | Pen-touch Operation - Quickly and easily create graphs using drag and drop | Simple interface - The Casio fx-CP400 has simple, easy-to-understand menu icons, menu bars, and toolbars and an interactive interface | Touch-panel operation by stylus or finger - The fx-CP400 offers intuitive stylus touch-panel operation that eliminates complicated key operations. Graphically display mathematical formulas by simply dragging and droppingthem into the graph area | Brand-new software keyboard - The fx-CP400 supports learning of basic functions usedby everyone, such as fractions, square roots,and trigonometric functions, advanced functions likedifferential calculus, complex compound numbers, andsigma calculations, as well as highly advancedcalculations such as piecewise and user-defined formulas | Computer Algebra System (CAS) - The CAS supports everything from Expand, Factor, Solve, and other basic commands to advanced commands like Fourier and Laplace transforms | eActivity application - An eActivity is like a digital worksheet that can be created andworked with on the fx-CP400. All of the powerful features andcapabilities of the fx-CP400 can be incorporated into aneActivity. In addition to performing the same calculations asthe Main application, an eActivity will accept text entry, justlike a word processor. Graphs, as well as Geometry andSpreadsheet data, can be stored in an eActivity file | Graph and Picture - The calculator comes pre-loaded with visuals such as a single image (still image) of the curve of an arched bridge. The use of real-life visuals as background images for functionssuch as the drawing of graphs overlaid on color images makes mathematics learning a more visually familiar experience | Graphing function - Display formulas and related graphs in the same color and highlight graph characteristics by displaying scale marks, grids, and coordinate values. The vivid colordisplay of the fx-CP400 improves the visibility of graphs and formulas | Geometry - Students can learn general theorems by drawing figures. Dropping a geometric figure into the Main application window will produce the numerical data for thefigure. An Animation function enables students to move geometric figures drawn onthe screen. The fx-CP400 supports drawing of conics using a focus | Spreadsheet application - Collected data can be organized and tabulated for analysis after statistical graphingis complete. Spreadsheet data also can be used in table calculations. In addition, thefx-CP400 supports the following functions: search, sort, data import from and export to lists, matrices, and variables, CellIf, and Histogram/Box-whisker graphing | Colour Link - The fx-CP400 features the Color Link function, which automatically links colors specified on the spreadsheet screen with colours used in graphs to support learning of functions by enabling visual confirmation of changes in values or trend | Differential Equation Graph application - The solution set of a differential equation can be represented graphically as a vectorfield, and solution curves can be drawn by providing initial conditions for theequation. First, second, and n-th order differential equations are supported | Financial application - This fx-CP400 application provides a total of 15 different financial calculations,including simple/compound interest, cash flow, amortization, depreciation, bondcalculation, and operating/financial leverage | | 3D Graph | Computer Algebra System | Colour Display | 500kb memory | Natural textbook display
