Definitional building blocks

The components that make up a symbolic definition can come

from a number of sources.

You can enter components directly from the keyboard. To

enter 2X

• From user variables

If, for example, you have created a variable called COST,

you could incorporate that into a definition either by typing

it or choosing it from the User menu (one of the sub-menus

of the Variables menu). Thus you could have a definition that

reads F1(X)=X

+COST.

To select a user variable, press a, tap , select

User Variables, and then select the variable of interest.
