Conic Section Graph Analysis
You can determine approximations of the following analytical results using conic section
graphs.
• Focus/vertex/eccentricity
• Latus rectum
• Center/radius
•
x
-/
y
-intercept
• Directrix/axis of symmetry drawing and analysis
• Asymptote drawing and analysis
After graphing a conic section, press
4
(G-SLV) to display the following graph analysis
menus.
