Graphing Methods
Numeric View:
M
This view displays a table of
evaluations. It also enables you
to enter specific values to be
evaluated. In most apps, this
view evaluates according to the
definitions specified in the
Symbolic view. It serves a
different purpose in other apps,
such as the statistics,
spreadsheet, and geometry apps.
Numeric Setup:
SM
(Settings)
This view enables you to set the
appearance of the Numeric
view (such as the starting
number, increment, and type of
table: automatic or build-your-
own).
The
option makes the
settings in Numeric view match
those that currently apply in the Plot view.
The HP Prime gives you the option of choosing one of three graphing methods. These methods determine the fineness of the plot:
•
adaptive
: this gives very accurate results and is used by default.
•
fixed-step segments:
this method samples
x
-values, computes their corresponding
y
-values, and then plots and connects the
points.
•
fixed-step dots
: this works like fixed-step segments method but does not connect the points.
You can change the current graphing method on page 2 of the Plot Setup view.
The three figures on page 18 illustrate the visual differences between these methods for the function f(
x
)=9*sin(e
x
).
