Quick-Start GRAPH FUNCTIONS The graphing capabilities of the CFX-9800G make it possible to graph complex functions using either rectangular coordinates (horizontal axis: x; vertical axis: y) or polar coordinates (horizontal axis: 0; vertical axis: r). Specifying the Graph Type Before drawing a graph, you must first specify the graph type (rectangular or polar) to suit the variables you will use. The following procedure shows how to specify rectangular coordinate graphing. 1. Enter the COMP Mode from the Main Menu. ) SET UP 2. Press SHIFT MENU to make the COMP Mode set up screen appear.
