Differential Equation Graph Window Operations

14-7 Differential Equation Graph Window

Operations

You can perform the following operations on the Differential Equation Graph window.

• Graph zooming and scrolling

• Modification of initial conditions (shifting the initial condition coordinates by dragging it)

• Configuring new initial conditions

• Tracing coordinates on a graph

• Graphing (slope field, phase plane, solution curves, general graphs) of an expression

or value dragged from an eActivity application or Main application to the Differential

Equation Graph window

Graph Zooming and Scrolling

You can use the menu commands and toolbar buttons shown below on the Differential

Equation Graph window to zoom and scroll a graph.

Pan

Zoom Out

Zoom In

Box

For details about these operations, see the applicable menu commands and toolbar buttons

in “Chapter 3 Using the Graph&Table Application”.

Configuring and Modifying Initial Conditions

You can modify existing initial conditions and configure new initial conditions on the

Differential Equation Graph window.

To modify an initial condition on the Differential Equation Graph window

Example: Input the Nth-order differential equation and initial conditions, and then draw the

solution curves. Next, modify an initial condition by dragging it on the Differential

Equation Graph window.
