Specify a graph.
2(X-CAL) cw
• At this time, the unit waits for input of a y-coor-
dinate value.
Input the
y-coordinate value.
d.c
Determine the corresponding x-coordinate value.
w
• If there is more than one x-coordinate value for a given y-coordinate value or
more than one y-coordinate value for a given x-coordinate value, use e and d
to move between them.
• The display used for the coordinate values depends on the graph type as shown
below.
• Polar Coordinate Graph
• Parametric Graph
• Inequality Graph
• Note that you can not determine a y-coordinate for a given x-coordinate with a
parametric graph.
• If there is only one graph, pressing 1 (Y-CAL) / 2 (X-CAL) directly displays
the x-coordinate/y-coordinate (selection of the graph is not required).
