Mathcad looks simple, and it is. It was created according to basic design principles to make it powerful, flexible and easy to use. In Mathcad:
• Everything appears in familiar math notation. If there’s a standard mathematical way to show an equation, operation, or graph, Mathcad uses it.
• What you see is what you get. There is no hidden information everything appears on the screen. When you print, the output looks just like the screen display.
• To create simple expressions, just type them. Mathcad uses the standard keys for standard mathematical operations.
• Typing aids make equations easier to enter. There are palettes for most mathematical operators and symbols.
• Fill in the blanks. Mathcad guides you through the creation of plots, integrals, and other mathematical expressions by laying down the framework and letting you fill in the blanks.Calculation features are modular. If you don’t want to use a feature-like complex numbers, units, or matrices-you can just pretend it isn’t there.
• The numerical algorithms are robust, standard, and predictable. Mathcad’s numerical algorithms for features like integrals, matrix inversion, and equation solving are reliable, standard methods.
• OLE support. Mathcad is an OLE2 application, providing drag and drop support of Mathcad objects into applications like Microsoft Word, in-place activation of Mathcad objects in client applications, and enhanced support for embedded OLE objects in Mathcad worksheets.
• Exchange data with other applications. Mathcad gives you easy-to-use tools to exchange data with spreadsheets, graphing packages, and other calculation applications.
• On-line help. Pressing [Fl] brings up an extensive on-line help system. Click on error messages, operators and functions and press [Fl] to display the relevant help screen. There’s no need to search for the topic you’re interested in. The User’s Guide includes more detail on all the features, with step-by-step instructions and illustrative examples. At the back of the User’s Guide is a complete cross-referenced index.
• Collaboration features. If you’re connected to an electronic mail system compatible with Microsoft Mail, mail worksheets to colleagues from right within Mathcad. And you have access to MathSoft’s Collaboratory server, a unique Web-based resource where you can exchange text messages, upload and download Mathcad files, and connect to a community of Mathcad users.
• Resource Center. A collection of Mathcad worksheets in an interactive, searchable Electronic Book, with links to resources on the World Wide Web. The Resource Center includes an Overview, Tutorial, Reference Tables, QuickSheets-prefab working templates for completing common mathematical tasks, ready for customization
and dragging into your own worksheets-and Practical Statistics, an overview of hypothesis testing and data analysis in Mathcad. Mathcad Professional includes in-depth sections on Solving and Programming drawn from The Mathcad Treasury, our best-selling Electronic Book. Visit MathSoft’s home page (www.mathsoft.com) directly from the Resource Center, or browse to any other resources on the World Wide Web. This chapter provides a quick introduction to Mathcad and demonstrates a few more advanced features like iterative calculation and plotting. After you read this chapter, you’ll have enough information to begin to solve your own problems in Mathcad. The rest of this User’s Guide describes all the features in detail, so you can learn more about any selected topic.
