2. BASIC USAGE OF Mathcad 13 Practice Start Mathcad and practice all shortcut keys (hot-key) listed in the four tables. 2. Basic Usage of Mathcad One can use Mathcad as ordinary graphic calculator in doing arith- metic computing like 3 + 5 = 8 , defining and graphing functions such as f ( x ) = 3 x 2 +3 . When perform arithmetic computation, you just need to click any blank area and enter the expression, then press = or = and [F9] key. The result will be immediately display. For example the fol- lowing key strokes 3+5= will produce 3 + 5 = 8 in the working area when aut-computation mode is on, or 3 + 5 = if the aut-computation mode is off. In later case, you will have to press [F9] key to generate the result. The difference between = and [F9] is the following, = only evaluate expressions when the mode of execution is set to be automatic. If aut-computation mode is turn off, = will only create a . after the expression. F9 causes Mathcad to carry out all computation in a given work-

You will have to use [F9] to tell Mathcad to do compu-tation if you turn o the automatic compute mode, which is desirable if you dont want to be bothered by Mathcad warning message. You can turn on/o the aut-computation mode through Math menu. 2.1. Some General Editing Methods. As in most window based text editors, we can use mouse to choose input starting point by moving mouse cursor to a desired point and click the right button. Every Mathcad equation, text paragraph, and plot in a worksheet is a separate object called region . We can also use mouse to select several regions and drag them around. To select one region, just move mouse over the region and click. A light bounding box will appear, which indicates the region is selected, as in the following screen shot for a selected math region,...
