2-D Math

2-D math is the default setting in Document Mode and Worksheet Mode. It is executable standard math notation displayed in a format similar to that found in business and education documents.  You can make it nonexecutable if needed.

 

ⅆⅆxx2ⅇ3 x

 

2-D math can be used in a document block as above or at a prompt ( ).

In contrast to 2-D math, Maple Input (1-D math) is only used at a prompt. It is executable Maple notation, such as a command for a mathematical operation that Maple can evaluate.

Basic Usage: 2-D Math and 1-D Math Input

2-D Math

Default. Executable standard math notation.

sin(x)ⅆx

cosx

You do not require a semicolon or colon to terminate the command or expression.

 

To switch between 1-D and 2-D math, press the F5 key or click the Math mode icon. Alternatively, access from the Insert>2-D Math menu.

 When using 2-D math, the Math mode icon is highlighted in the toolbar.

In Worksheet and Document modes with 2-D math, the cursor appears with a gray underbar and the input font is black. To change the appearance of 2-D math, modify the character styles 2D Input (for Worksheet mode) and 2D Math (for Document mode).

1-D Math

Executable Maple notation. An expression in the Maple language.

factor(x^2 + 2*x + 1);

(x+1)2

You do not require a semicolon or colon to terminate the command or expression.

 

To switch between 1-D and 2-D math, press the F5 key or click the Text mode icon. Alternatively, access from the Insert>Maple Input menu.

 When entering Maple input and text, the Text mode icon is highlighted in the toolbar.

To customize your interface so 1-D math (Maple Input) is the default at any prompt, change the Input Display setting in the Display tab of the Options Dialog.

In Worksheet and Document modes with 1-D math, the input font is red.

Executing 2-D Math

Worksheet Mode

• 

All 2-D math in a worksheet can be executed and displayed by pressing the Enter key.

• 

For 2-D math in Document Blocks in a worksheet, see the following section.

Document Mode

Execute 2-D math in Document Mode and Document Blocks by using any of the following methods.

• 

Press Alt + Enter (Alt + Return, for Mac) or Ctrl + = (Command + =, for Mac). This evaluates and displays results inline.

• 

Use the Evaulate menu item Evaluate and Display Inline. (This can also be invoked through the context-sensitive menu.)

• 

Use the Evaluate menu item Evaluate.

• 

Press Enter. This evaluates and displays results on the next line.

You can make a 2-D math expression nonexecutable. For more information, see 2-D Math Details.

Using a Palette with 2-D Math Input

To use a palette with 2-D math:

  

 1. Ensure the palette you require is visible. If necessary, from the View menu, select Palettes>Arrange Palettes.

  

 2. With your mouse, click a palette expression. The expression is displayed in 2-D math notation in the execution group of the worksheet.

  

 4. The first option is highlighted. Enter your expression, and if necessary use the Tab key to move to the next item.

  

 5. Press Enter.

• 

Palettes make entering expressions more efficient and reduce the possibility of introducing typing errors.

• 

Your worksheet uses standard notation for mathematical content.

Converting 1-D to 2-D Math

To convert 1-D to 2-D math:

  

 1. Enter an expression in 1-D math notation. (Press F5 to switch between 1-D and 2-D math entry.)

  

 2. From the Context Panel, select Convert To>2-D Math Input. The expression is now displayed in 2-D math input notation.

  

 3. Press Enter to evaluate the expression.

Important: Mixed 1-D math and 2-D math is not supported and not recommended stylistically. You cannot mix 1-D and 2-D math inside one command. For example, the following is not supported.

fprocxx^2end proc;

Warning, inserted missing semicolon at end of statement

x2

You can, however, have a well formed 2-D expression and a well formed 1-D expression in the same execution group. For example,

fprocx x end proc; x^2;

f:=procxxend proc

x2

The Typesetting Rule Assistant is a graphical user interface for changing the current typesetting rules. These rules control the input and typesetting of 2-D math within the standard worksheet interface. For more information, see Typesetting Rule Assistant.

 

The 2-D Math Details page gives more information on entering 2-D math.

Formatting Options with 2-D Math

The Format menu provides the following options which are useful for 2-D math:

• 

Modify the font attributes of the 2-D math expression.

• 

Access the Numeric Formatting and Units Formatting dialogs.

• 

Convert To — For details, see the Convert To help page.

Most of these options are also available through the Context Panel. For more information on the Context Panel, see Context Panel.
