**Writing an Expression in Maple**

We are going to begin this tutorial by
defining a function. Since we want this function to look as math-like
as possible, we would like our function to have the correct
mathematical notation. There are two ways math expressions can be
written in Maple. We can go to *View*
on the Menu and choose
*Palettes*
. Maple will then give us three choices:
*Symbol, Expression, *
and
* Matrix*
. If the first method is not used, one could choose to
use Maple *Input*
from
*Insert*
on the same Menu.

*--View*
. . .
*Palettes*
. . .
*Expression*

Choose the integral sign without limits from the
*Expression* palette:
" will appear on your screen. Now fill in the
question marks with the expression of your choice. (Yet again you can
choose
to either write out the Maple language for the function of your choice
or you can use the Expression Palette). We
want to choose "
, " and then use x as the variable in place of the
?'s above. Any expression you choose to take the place of the
question mark will appear in the area just below the picture menu bar.
Once you have filled in the ?'s pr
ess the "T" in the picture menu bar to continue writing.

*--Input*
. . .
*Insert*

A ? will appear and the area just below the picture menue bar will be open for writing. Here you have to type in the expression you desire.

You have entered a function in Maple.
