Once you’ve created a worksheet, you will probably want to save or print it. This section explains how to save and print in Mathcad. Saving a worksheet To save the file, • Choose Save from the File menu or click on the disk icon in the toolbar. If the file has never been saved before,…

Mathcad can show both two-dimensional Cartesian and polar graphs, contour plots, surface plots, and a variety of other three-dimensional plots. These are all examples of plot regions. This section describes how to create a simple two-dimensional graph showing the points calculated in the previous section. Creating a graph To create a graph in Mathcad, click…

Mathcad can do repeated or iterative calculations as easily as individual calculations. Mathcad uses a special variable called a range variable to perform iteration. Range variables take on a range of values, such as all the integers from 0 to 10. Whenever a range variable appears in a Mathcad equation, Mathcad calculates the equation not…

Mathcad lets you enter equations and text anywhere in the worksheet. Each equation or piece of text is a region. Mathcad creates an invisible rectangle to hold each region. A Mathcad worksheet is a collection of such regions. To see these regions, choose Regions from the View menu. Mathcad will display blank space in gray…

Mathcad handles text as easily as it does equations, so you can make notes about the calculations you are doing. To begin typing text, click in an empty space and do any one of the following: choose Text Region from the Insert menu, press the doublequote key (“), or click on the text region button…

Definitions and variables Mathcad’s power and versatility quickly become apparent once you begin to use variables and functions. By defining variables and functions, you can link equations together and use intermediate results in further calculations. The following examples show how to define and use several variables. Defining variables To clear the previous equation and define…

Although Mathcad can perform sophisticated mathematics, you can just as easily use it as a simple calculator. To try your first calculation, follow these steps: • Click anywhere in the worksheet. You see a small crosshair. Anything you type appears at the crosshair. + • Type 15-8/104.5= . When you press the equals sign, Mathcad…
