Storing Functions

kQuick Graphing of an Expression Using Drag and Drop

You can use the following procedure to graph a single function, even when you have multiple functions selected on the Graph Editor window.

u ClassPad Operation

(1)Tap the tab of the sheet that contains the function you want to graph to make it active.

(2)Drag the function you want to graph to the Graph window.

Tip

The above drag and drop procedure can be used to graph a function, regardless of whether the function’s check box is selected or cleared.

When you quick graph a function using drag and drop, the function is always treated as a “y=” expression, regardless of the graph type specified for the function.

Up to 30 of the graphs you draw in the Graph window are stored in memory as you draw them. This includes graphs drawn from Graph Editor window functions, graphs drawn using the Sketch functions (Tangent, Normal, Inverse), and graphs drawn using the drag and drop operation described above. Though you can draw more than 30 graphs at one time, any graphs after the 30th are not stored in memory.

All of the Graph window graphs that are currently stored in memory are redrawn when you scroll the Graph window or tap the [ReDraw] command on the amenu. Since only 30 graphs are

stored in memory, anything drawn after the 30th graph is not redrawn. Keep this limitation in mind when you draw a large number of graphs at the same time.

Saving Graph Editor Data to Graph Memory

Graph memory lets you store all of the expressions and their related information to a file for later recall.

Each graph memory file contains the following data:

Functions on all five Graph Editor sheets (up to 100 functions)

Whether the check box next to each function is selected (checked) or cleared (unchecked)

The line style of each function

The graph type of each function

The View Window settings

Which sheet is currently active
