CHAPTER 4
When the graph with the cursor pointer indication is changed in either of the
previous two methods, the equation displayed at the upper left corner of the display
also changes to the one for the newly selected graph.
(The previous example shows the screen after the cursor pointer is moved from the
equation "Y1 = –(x+2)
* Since the X and Y coordinates vary depending on the location of the cursor pointer, the
displayed values may differ from those in the examples.)
Free-moving cursor:
The above explanation showed the methods of moving the cursor on a graph. The
cursor can also be moved freely on the screen.
There are two ways to set the cursor to the free-moving mode.
In either method, the screen must be in the graph display mode (not in the TRACE
mode).
1
Press any of <, >, ≥, and ≤ to display the cursor pointer (flashing)
on the display. Press <, >, ≥, or ≤ to move the cursor freely on the
display.
2
Select a point on the display using the touch-pen.
When the screen is touched, the " " mark appears on the display. Touch the same
location again to display the cursor pointer. After the cursor pointer appears on the
display, <, >, ≥, and ≤ can be used to move the cursor pointer dot
by dot. The touch-pen can be used to designate a new location.
