Mathcad's interactive, visual interface makes it easy to set up, analyse, solve and document all kinds of technical problems, using real mathematical notation which you can integrate on-screen with text and graphics. With Mathcad, all your formulae and equations are clearly visible within your document, so it's easy to verify and validate your results -- and they're all live too, so whenever you change a variable, Mathcad automatically updates your entire worksheet!

Mathcad PLUS 6.0 Professional Edition takes a gigantic leap forward in Mathcad capability. For example, you get a new set of built-in procedural operators which you can use to build your own "live" functional programs right in your Mathcad document. Just click on the operators to define local variables, loops, branches, nested data structures and recursive functions. And in practically no time, you'll be creating programs that operate on scalars, vectors, matrices and more.

With the new visualisation tools in Mathcad PLUS 6.0, you'll be able to look at your work in some helpful new ways. Graphs are easier to create and format, new graph types have been added, backplanes and new axis options are now available for 3-D graphs. You can import bitmap images into your documents as matrices and manipulate them with all of Mathcad's functionality. And there are new animation capabilities to bring your work to life, animating graphs, numerical results and images so you can view systems over time or as any other variable changes.

You get  control over the look of your document too: Mathcad PLUS 6.0 lets you put "live" equations straight into text areas, highlight text in colour to bring attention to key points, justify and centre text for a more effective presentation. And for full word processing capabilities, you can now export complete Mathcad documents to your word processor.

There are enhanced data analysis functions and statistical routines, and QuickSheets to to guide you quickly through many of Mathcad PLUS 6.0's new (and existing) features. And Mathcad PLUS 6.0 makes it easy to share your Mathcad worksheets with colleagues, coworkers and customers, with built-in email, network and World Wide Web connectivity.

The full Mathcad 6.0 product range, including add-on Electronics Books and Function Packs, is described in Mathematical Solutions.
