...Enter a Simple Expression?


In Maple, mathematical expressions, such as , can be entered in a natural, textbooklike notation. In Maple, this is called 2D Math notation. The following examples demonstrate the process of entering expressions.
To begin, create a new document in Document mode. To begin entering a 2D mathematical expression, ensure that you are in Math mode. In this mode, the cursor is inside a box with a dotted outline that indicates the boundaries of the mathematical expression. By default, all new documents created in Document mode start in Math mode so that you can begin entering mathematical expressions immediately. To switch between Math mode and Text mode, press [F5].
A video demonstration of the following examples is available online.

Example:


Ensure that you are in Math mode, and follow the steps below to enter the expression .

Type , then . Maple's Math mode treats the juxtaposition of a constant and a variable as an implicit multiplication.


2

Type the division [/] character.


3

Type .


4

To bring the cursor back onto the base line, press the right arrow [→] key on your keyboard.


5

Type [+]. There is no need to type a space, as Maple automatically adjusts the spacing for you.


6

Repeat steps 1 through 4 to type .
