Opening a worksheet To work on a worksheet that you saved before, choose Open from the File menu.Mathcad prompts you for a name by displaying the Open dialog box. You can locate and open a Mathcad worksheet from other directories or drives just as you would in any other Windows application. At the bottom of the…
you move and edit the regions in a Mathcad worksheet, they may end up overlapping one another. Overlapping regions don’t interfere with each other’s calculations, but they do make worksheets hard to read. A good way to determine whether regions overlap is to choose Regions from the View menu. Mathcad will display blank space in…
Once regions are selected, you can align them either horizontally or vertically by choosing Align Regions from the Format menu. This is a pull-right menu. Drag the mouse to the right to display two additional choices: Across and Down. You can also choose these commands by clicking on the appropriate button on the toolbar. When…
.A This section describes how to rearrange expressions, graphics and text in your worksheets. The techniques described here work equally well for everything in your worksheet: equations, plots, sketches and text. Before you use the methods in this section, click in the empty space between regions to turn the cursor into a crosshatch. You can…
You can avoid having to repeatedly backspace over parts of an expression by choosing Cut from the Edit menu. This will delete whatever is between the editing lines place it on the clipboard. The following example shows how you can use the cut command to delete a significant part of an expression. Suppose you want…
The minus sign that means “opposite of” uses the same keystroke as the one that means “subtract.” To determine which one to insert, Mathcad looks at where the vertical editing line is. If it’s on the left, Mathcad inserts the “opposite of” minus sign. If it’s on the right, Mathcad inserts the “subtract” minus sign.…
To delete an operator connecting two variable names or constants: • Place the editing lines after the operator. • Press the [BkSp] key. Now you can easily insert a new operator to replace the one you deleted just by typing it in.You can also delete an operator by placing the editing lines before it and pressing…
This section describes how to make changes to an existing expression. The simplest changes you can make are discussed in “Changing a name or number” on page 55. Here, the underlying tree structure of a math expression doesn’t matter. As a result, the equation editor behaves very much like a text editor. Most difficulties in…
A common way to show multiplication between two variables on a piece of paper is to place them next to each other. For example, expressions like ax or a(x + y) are easily understood to mean “a times x” and “a times the quantity x plus y,” respectively. This cannot be done with Mathcad variables…
our can create many mathematical expressions by simply typing in a stream of characters. Certain characters, like letters and digits, make up parts of names and numbers. Other characters, like * and +, represent “operators.” For example, if you type the characters This chapter describes the mechanics of creating mathematical expressions and making changes in…
