Tip: To turn off any stat
data plots, press ‡ 5 or
use † to deselect them.
Refer to Chapter 16.
Note: The Fields format is
critical, depending on the
order of the equation
(page 197).
Note: Valid Axes settings
depend on the Fields format
(pages 190 and 197).
Note: Depending on the
Solution Method and Fields
formats, different Window
variables are displayed.
Tip: „ Zoom also changes
the viewing window.
178 Chapter 11: Differential Equation Graphing
To graph differential equations, use the same general steps
used for y(x) functions as described in Chapter 6: Basic Function
Graphing. Any differences are described on the following pages.
Set Graph mode (3)
to .
DIFF EQUATIONS
Also set Angle mode,
if necessary.
Define equations and,
optionally, initial
conditions on Y= Editor
(¥ #).
Select (†) which
defined equations to
graph.
Set the display style for
an equation.
