CHAPTER 4
(7) Trace function for moving the cursor pointer on the graph
The trace function allows the cursor pointer to be moved on the graph and displays
the coordinates.
• Set to the TRACE mode.
Press
.
As shown on the right, a flashing cursor pointer
appears on the equation curve. The X and Y coordi-
nates of the cursor pointer position are displayed at the bottom of the screen.
• Moving the cursor pointer
There are two ways to move the cursor pointer on a graph.
1
Using < >:
• When < is pressed, the cursor pointer moves to the left on the equation curve.
• When > is pressed, the cursor pointer moves to the right on the equation curve.
2
Using the touch-pen:
• With the touch-pen, touch the location on the display.
The cursor pointer moves to the selected position.
A “
” mark appears on the screen. This mark indicates
the selected position.
• If the position is acceptable, touch inside the “
” mark.
This enters the selected position, and moves the cursor
to a point on the curve inside the “
” mark. (The
location to which the cursor moves is a calculation
point on the graph within the “
” mark, which is
obtained by the calculator’s internal processing. If the
graph slope is steep and there is no calculation point
within the “
” mark, the cursor moves to a calculation
point nearest to the “
” mark. Therefore, the cursor pointer may be positioned
outside the “
” mark in some cases.)
* If the displayed “
” mark is not located at the selected position, touching another position with
the touch-pen moves the “
” mark to the newly selected position.
