14-1 Inputting an Expression

Use the 3D Graph Editor window to input 3D Graph application expressions.

Using 3D Graph Editor Sheets

3D Graph Editor sheet operations are similar to the sheet operations of the Graph & Table application. For
more information, see "Using Graph Editor Sheets" on page 99.
Note:
The Graph & Table application allows simultaneous graphing of multiple functions, as long as they are
on the same sheet. With the 3D Graph application, however, you can graph only one function at a time.
