• To change the graph line style, press 1(SEL+S) after step 4.
• With WEB Graph, you can specify the line type for a y = f ( x ) graph. The line type setting is
valid only when "Connect" is selected for "Draw Type" on the Setup screen.

11. Graphing a Conic Section

k Graphing a Conic Section
You can use the Conic Graphs mode to graph parabolas, circles, ellipses, and hyperbolas.
You can input a rectangular coordinate function, polar coordinate function, or parametric
function for graphing.
1. From the Main Menu, enter the Conic Graphs mode.
2. Select the function type.
1(RECT).... {rectangular coordinate}
2(POL).... {polar coordinate}
3(PARAM).... {parametric}
