Getting Acquainted

uGraphs

As a general rule, graph operations are shown on

facing pages, with actual graph examples on the right

hand page. You can produce the same graph on your

calculator by performing the steps under the Procedure

above the graph.

Look for the type of graph you want on the right hand

page, and then go to the page indicated for that graph.

The steps under “Procedure” always use initial RESET

settings.

The step numbers in the “Set Up” and “Execution” sections on the left hand page

correspond to the “Procedure” step numbers on the right hand page.

Example:

Left hand page Right hand page

uCommand List

The PRGM Mode Command List (page 8-7) provides a graphic flowchart of the various

function key menus and shows how to maneuver to the menu of commands you need.

Example: The following operation displays Xfct: [VARS]-[FACT]-[Xfct]

uPage Contents

Three-part page numbers are centered at the top of

each page. The page number “1-2-3”, for example,

indicates Chapter 1, Section 2, page 3.

Supplementary information is shown at the bottom of each page in a “ (Notes)” block.

indicates a note about a term that appears in the same page as the note.

# indicates a note that provides general information about topic covered in the same section
