1 Document Mode

Using the Maple software, you can create powerful interactive documents. You can visualize and animate problems in two and three dimensions. You can solve complex problems with simple point-and-click interfaces or easy­to-modify interactive documents. Y ou can also de vise custom solutions using the Maple programming language. While you work, you can document your process, providing text descriptions.

1.1 Introduction

Maple has two modes: Document mode and Worksheet mode. Using Document mode, you can quickly perform calculations. You can enter
a mathematical expression, and then evaluate, manipulate, solve, or plot it with a few keystrokes or mouse clicks. This chapter provides an overview of Document mode.
Document mode sample:
Find the value of the derivative of at .
Integrate over the interval .
=
Worksheet mode is designed for interactive use through commands and programming using the Maple language. The Worksheet mode supports the features available in Document mode described in this chapter . After revie w-

Important: In every Maple document, you can use Document mode and
Worksheet mode. Using either mode:
1.2 In This Chapter • 3
You have access to the full mathematical engine.
You can create high quality interactive documents: easy-to-use compu­tational tools, presentations, or publications.
Interactive document features include:
Embedded graphical interface components, like buttons, sliders, and check boxes
Automatic execution of marked regions when a file is opened
Tables
Character and paragraph formatting styles
Hyperlinks
These features are described in Chapter 6, Creating Mathematical Docu- ments (page 231).
Note: This chapter was created using Document mode. All other chapters were created using Worksheet mode.

1.3 Simple Mathematical Expres­sions
In Document mode, you can enter two types of content: Text and Math. The Text mode and Math mode icons at the left end of the toolbar indicate the current mode. The toolbar is located near the top of the Maple window, im­mediately below the menu bar.
To switch between Text and Math modes, press the F5 key. (Alternatively, click the Text mode or Math mode toolbar icon.) Consequently, it is easy to enter sentences containing text and inline mathematical expressions.
1.3 Simple Mathematical Expressions • 5
Entering mathematical expressions, such as , , and , is natural in Math mode.

Rational Expressions (Fractions)

To enter a fraction:
1. Enter the numerator.
2. Press the forward slash (/) key.
3. Enter the denominator.
4. To exit the denominator, press the right arrow key.

Powers

To enter a power:
1. Enter the base.
2. Press the caret (^) key (Shift + 6).
3. Enter the exponent, which displays in math as a superscript.
4. To exit the exponent, press the right arrow key.

Products

To enter a product:
1. Enter the first factor.
2. Press the asterisk (*) key, which displays in math as .
3. Enter the second factor.
6 • 1 Document Mode
Implied Multiplication
In most cases, you do not need to include the multiplication operator, . Insert a space character between two quantities to multiply them.
Note: In some cases, you do not need to enter the multiplication operator or a space character. For example, Maple interprets a number followed by a variable as multiplication.

Other Expressions

It is also easy to enter mathematical expressions, such as:
Piecewise-continuous functions:
Limits:
Continued fractions:
and more complex expressions. For information, see Entering Expres- sions (page 10).
8 • 1 Document Mode

1.4 Evaluating Expressions

To evaluate a mathematical expression, place the cursor in the expression and press Ctrl + = (Command + =, for Macintosh). That is, pr ess and hold the Ctrl (or Command) key, and then press the equal sign (=) key.
T o the right of the expression, Maple inserts an equal sign and then the v alue of the expression.
=
You can replace the inserted equal sign with text or mathematical content.
To replace the equal sign:
1. Select the equal sign. Press Delete.
2. Enter the replacement text or mathematical content. For example, you can replace the equal sign with the text "is equal to".
is equal to
In mathematical content, pressing Enterevaluates the e xpression and displays it centered on the following line. The cursor moves to a new line below the output.
By default, Maple labels output that is generated by pressing Enter. For in­formation on equation labels, see Equation Labels (page 59). In this manual, labels are generally not displayed.
1.5 Editing Expressions and Updating Output • 9
In text, pressing Enter inserts a line break.
You can use the basic algebraic operators, such as and , with most expressions, including polynomials—see P olynomial Algebr a (page 126)—and
matrices and vectors—see Linear Algebra (page 135).

=
1.5 Editing Expressions and Updat­ing Output
One important feature of Maple is that your documents are live. That is, you can edit expressions and quickly recalculate results.
To update one computation:
1. Edit the expression.
2. Press Ctrl + = (Command + =, for Macintosh) or Enter. The result is updated.
To update a group of computations:
1. Edit the expressions.
2. Select all edited expressions and the results to recalculate.
3. Click the Execute toolbar icon . All selected results are updated.
To update all output in a Maple document:
10 • 1 Document Mode
Click the Execute All toolbar icon . All results in the document are updated.

1.6 Entering Expressions

Mathematical expressions can contain the following symbols.
Numbers: integers, rational numbers, complex numbers, floating-point
values, finite field elements, , , ...
Operators: , , , /, , , , , ...
Constants: π, e, ...
Mathematical functions: sin(x), , Γ(2), ...
Names (variables): x, y, z, α, β, ...
Data structures: sets, lists, Arrays, Vectors, Matrices, ... Maple contains over a thousand symbols. For some numbers, operators, and
names, you can press the corresponding key , for e xample, 9, =, >, or x. Most symbols are not available on the keyboard, but you can insert them easily using two methods.
To insert a symbol, you can use:
Palettes
Symbol names

Palettes

Palettes are collections of related items that you can insert by clicking or dragging. Palettes contain:
Numbers and constants, like i (the imaginary unit), π, and . For example,
see the Common Symbols palette (Figure 1.1).
1.6 Entering Expressions • 11
Layouts, like an item with a superscript and subscript. For example, see
the Layout palette (Figure 1.2).
Mathematical operations, like a definite integral with placeholders for the integrand, variable of integration, and endpoints of the interval of integration. For example, see the Expression palette (Figure 1.3).
Specialized tools. For example, see the Matrix palette (Figure 1.4). For information on the Matrix palette, see Creating Matrices (page 135).

Using Palettes
To insert a palette item:
1. In the palette, click the item to insert. The item is inserted at the cursor location.
2. If the item has colored placeholders, specify values for them.
To move to the next placeholder, press the Tab key.
