What Is Mathcad?
Mathcad is the primary piece of the Mathsoft Calculation Management Suite. Together
the suite enables engineers to simultaneously design and document their work while
centrally managing it for reuse, auditing, publishing and collaboration throughout the
entire development process.
Mathcad delivers all the solving capabilities, functionality, and robustness needed for
calculation, data manipulation, and engineering design work. Mathcad allows you to
document your calculations in the language of mathematics, because Mathcad
combines a powerful computational engine, accessed through conventional math
notation, with a full-featured word processor and graphing tools.
You can type equations as you’re used to seeing them on paper.
Simply type in your equations, then see them display with an
instant result, along with as much text you want to accompany
the math. Mathcad makes it easy to communicate the rationale and assumptions behind
your calculations enabling design quality assurance.
You can use Mathcad equations to solve both symbolical and numerical equations. You
can place text anywhere on the worksheet and add two- and three-dimensional graphs
to the page. You can even illustrate your work with images taken from another
application. Mathcad takes full advantage of Microsoft’s OLE 2 object linking and
embedding standard to work with other applications, supporting drag and drop and in-
place activation as both client and server.
Mathcad lets you easily mix and convert between unit systems, catching unit mistakes
by checking your worksheets for dimensional consistency. You can work in your
preferred unit system or switch to another system for a particular set of equations.
Mathcad’s powerful programming and scripting capabilities are not introduced in this
introductory User’s Guide . Visit online Help, the Programming tutorial, and the
Developer’s Reference for learning how to program in Mathcad.
Mathcad comes with online Tutorials ; QuickSheets showing working examples of
Mathcad functions and applications; and Reference Tables with math, science, and
engineering formulas. These live worksheets are found under the Help menu or from
