u Inserting a Function into an Existing Expression
In the Math input mode, you can make insert a natural input function into an existing
expression. Doing so will cause the value or parenthetical expression to the right of the
cursor to become the argument of the inserted function. Use !D(INS) to insert a
function into an existing expression.
u To insert a function into an existing expression
Example To insert the function into the expression 1 + (2 + 3) + 4 so the
parenthetical expression becomes the argument of the function
1. Move the cursor so it is located directly to the left of the part of the expression that
you want to become the argument of the function you will insert.
2. Press !D(INS).
• This changes the cursor to an insert cursor (').
3. Press !x( ) to insert the function.
• This inserts the function and makes the parenthetical expression its argument.
u Function Insert Rules
The following are the basic rules that govern how a value or expressions becomes the
argument of an inserted function.
• If the insert cursor is located immediately to the left of an open parenthesis, everything
from the open parenthesis to the following closing parenthesis will be the argument of the
inserted function.
• If the input cursor is located immediately to the left of a value or fraction, that value or
fraction will be the argument of the inserted function.
