Chapter 5:
Differential Equation Graph Application
This chapter explains how to use the Differential Equation Graph
application, which you can use to investigate families of solutions to
ordinary differential equations.
The Differential Equation Graph application has the following two types of
windows.
1 Differential Equation Editor window
Use this window to input expressions ([DiffEq] tab) and initial conditions
([IC] tab) for graphing. You also can input
f
(
x
) type functions ([Graphs]
tab).
2 Differential Equation Graph window
This window shows the graph of the expression that you input into the
Editor window.
