Trace Function For Moving The Cursor Pointer On The Graph - Sharp EL-9650 Operation Manual

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 "

to a point on the curve inside the "
location to which the cursor moves is a calculation
point on the graph within the "

graph slope is steep and there is no calculation point
within the " " mark, the cursor moves to a calculation
point nearest to the "
outside the " " mark in some cases.)
