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:

u u u u u Command 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]
u u u u u Page 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.
