3.On the Differential Equation Graph window, tap the coordinates that you want to specify as the new initial condition.

• This will set the coordinates as the new initial condition and draw a solution curve.

• The newly configured initial condition is added to the initial condition editor. To view it, tap the [IC] tab.

Configuring Differential Equation Graph View Window Parameters

You can set a number of graphing parameters on the View Window dialog box. This dialog box contains two tabs.

The [Window] tab lets you set the window values and steps used for graphing a field. The [Solutions] tab contains parameters used for graphing solution curves.

uTo configure differential equation graph View Window settings

1.Tap 6 to display the View Window dialog box.

2.Input the required parameters on the [Window] and [Solutions] tabs.

• See “Differential equation graph View Window parameters” below.

3.After the settings are the way you want, tap [OK].

Differential equation graph View Window parameters [Window] tab
Setting

Description

xmin, xmax

Minimum/maximum value along the (horizontal) x-axis

 

 

ymin, ymax

Minimum/maximum value along the (vertical) y-axis

 

 

Field

Specifies display of arrow, line or nothing.

 

 

Steps

Number of steps or field lines used for graphing a field

 

 

[Solutions] tab

The variable assignments available on the [Solutions] tab vary depending on the graph type selected with the Graph Editor. Some graph types have preset assignments for the independent, x-axis, and y-axis variables. If a value is preset for the current graph type the value will still be displayed on the Solutions tab, but you will not be able to change it.
