Overview of Steps in Graphing Differential

Equations

To graph differential equations, use the same general steps used for

y(x)

functions as

described in Basic Function Graphing. Any differences are described on the following
pages.

Graphing Differential Equations

1. Set

Graph

mode (

3) to

DIFF

EQUATIONS

. Also set

Angle

mode,

if necessary.

2. Define equations and, optionally, initial

conditions on Y= Editor (

8 #).

3. Select (

†) which defined functions to

graph.
