• If there is more than one
y
more than one -coordinate value for a given
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
parametric graph.
• If there is only one graph, pressing 1 (Y-CAL) / 2 (X-CAL) directly displays
x y
the -coordinate/ -coordinate (selection of the graph is not required).
