Free Advice on using Derive 5. Here you'll find the first two chapters of the book "Introduction to Derive 5" in PDF format, readable with the freely available Adobe Acrobat PDF reader.
The following are a few of the many innovations incorporated into the previous version, DERIVE for Windows version 4.
Command toolbar: Issuing frequently used DERIVE commands is as easy and effortless as a mouse click. Just highlight an expression and click on the desired operation on the command toolbar. The algebra window toolbar includes buttons for authoring, simplifying, approximating, solving, differentiating, and integrating expressions. Helpful tool tips indicate the purpose of each button. [go to top]
Substitution dialogs: Simply click on the variables from the list that DERIVE for Windows presents to you and then enter the desired value for that variable. To change a value for a variable already entered, use the arrow keys or the mouse to select the variable and edit its value.
File menu commands: Navigate through directory trees using standard Windows dialog boxes to load, save, and append files.
Context sensitive help: Press the F1 key to instantly obtain detailed help on any command dialog box. Extensive on-line help is available for DERIVE's built-in mathematical functions and operators. The utility files distributed with DERIVE are also fully documented on-line. [go to top]
Entering expressions: Besides typing from the keyboard, a new expression may be created by clicking on the Greek toolbar, pasting from the clipboard, or inserting the highlighted expression.
Greek toolbar: To enter Greek variable names and mathematical symbols on the author line simply click on the desired name or symbol in the Greek toolbar. Or, if you prefer, enter them using Ctrl key combinations. [go to top]
2D matrix input: After entering the dimensions of the matrix, DERIVE for Windows displays a two-dimensional expression entry array ready for your input. You can move to each matrix element using the mouse or direction keys.
Multiple expression highlighting: Click and drag with the mouse to highlight multiple expressions. Then you can easily remove them, copy them to the clipboard, or drag and drop them at a new location. [go to top]
Subexpression highlighting: Click on an expression to highlight the entire expression. Then click on a subexpression to highlight it. Just keep clicking to highlight more deeply nested subexpressions. [go to top]
Fast and accurate plotting: Plotting is as easy as highlighting an expression and clicking on the Plot! menu command or corresponding toolbar button. Almost instantly your 2D or 3D plot appears. [go to top]
Command toolbars: The 2D and 3D plot window toolbars make it easy to annotate and print plots, position the plot region, and scale the plot.
Status Bars: Important information about the current plot window is displayed in the status bar. The 2D-plot window status bar displays the current coordinate system selected, the cross and centre coordinates, and the scale units. The 3D-plot window status bar displays the eye and center position as well as the length of the box. [go to top]
Copying plots: Copy the plot window to the clipboard by a simple keystroke combination or use a drag box to select a portion of the screen. Paste the image into a file using your favourite bitmap-compatible word processor or graphics program. [go to top]
Cross positioning: With one click of the mouse move the cross to any point in a 2D plot window and view the point's coordinates displayed on the status bar.
Plot range: Use a drag box to specify the boundaries of a new 2D plot range or enter numerical values for the boundary coordinates in a dialog box. [go to top]
Plot annotation: Single-line annotations can be placed at any location in a 2D-plot window. They can include Greek letters or mathematical symbols as well as normal text. Each annotation can be displayed in any colour -- for example, to match the colour of a particular plot line.
Page setup: Customize the header and footer lines of DERIVE expression and plot printouts. Use
&-Macros to include the file name, page number, date, and time in headers and footers. You can also specify the page size, margins, and orientation of DERIVE printouts. [go to top]
Print preview: Preview the print image of DERIVE expressions and plots before actually sending them to the printer. Zoom the preview in and out and view one or two pages at a time.
Printer support: If your printer is set up for Windows, it is set up for DERIVE. Support is provided for all types of black & white and colour printers. [go to top]
System requirements: A PC compatible computer with at least 8 megabytes of memory running Microsoft Windows 95, 98, ME, 2000, Professional, NT, (or Windows 3.1x with Microsoft Win32s software if you use the previous version DERIVE v4). DERIVE is a state-of-the-art 32-bit program that takes full advantage of the memory available on your computer. DERIVE for Windows version 5 is distributed on CD-ROM.
