Text editing

This section describes Mathcad features for editing existing text. This includes changing the words themselves, either manually or by clicking and typing. It also includes changing the way the words look by changing various font properties, and changing the way they’re arranged by changing the alignment within text regions. Moving the insertion point in text…

Boolean operators

Unlike other operators, the boolean operators can return only a zero or a one. Despite this, they can be very useful. You have already seen an example in Figure 12-3 showing how a boolean operator made a variable upper limit of summation possible. Chapter 12, “Operators,” shows how a boolean operator makes it possible to determine the array index…

Equations in text

This section describes how to insert equations into your text regions. Equations inserted into text have the same properties as those in the rest of your worksheet. You can edit them using the methods described in Chapter 3, “Editing Equations.” Entering an equation into text can affect the spacing between the lines of a text…

Integrals

You can use Mathcad’s integral operator to numerically evaluate the definite integral of a function over some interval. As an example, here’s how you would evaluate the definite integral of sin(x)2 from 0 to n/2 . Follow these steps: • Click in a blank space and type &. An integral appears, with placeholders for the  integrand, the limits…

Inserting text

This section describes how to create text regions in Mathcad. Text regions are useful for inserting any kind of text into your worksheets and templates: comments around the equations and plots in your worksheet, blocks of explanatory text, background information, instructions for the use of the worksheet, and so on. There is no limit on…

Inserting Mathcad objects into other applications

Just as you can insert objects into a Mathcad worksheet from other OLE2-compatible applications, you can insert Mathcad objects-either entire Mathcad worksheets or selected Mathcad regions-into other applications. The methods of doing so are nearly the same as those outlined in the previous section for inserting objects into Mathcad. They depend, however, on the extent…

Summations and products

The summation operator sums an expression over all values of an index. The iterated product operator works much the same way. It takes the product of an expression over all values of an index To create a summation operator in your worksheet: • Click in a blank space. Then type [Ctrl][Shift]4. A summation sign with four placeholders appears…

Pasting an object into a worksheet

Instead of inserting an object through the Insert Object dialog box, you can copy an object from a source application to the clipboard and paste it into Mathcad. This method is particularly useful when you’ve already created the object in another application and you don’t want to insert an entire file. To insert an embedded…
