Differences in Diff Equations and Function Graphing

This module assumes that you already know how to graph 

 functions as described in 

Basic Function Graphing. This section describes the differences.

Use 

3 to set 

before you define differential equations or set 

Window variables. The Y= Editor and the Window Editor let you enter information for the 
current Graph mode setting only.

8. Graph the selected functions (

8 %).

Use t0 to specify when initial conditions occur. 
You can also set t0 in the Window Editor.
Use yi to specify one or more initial conditions 
for the corresponding differential equation.
You can define differential equations y1'(t) 
through y99'(t).
