k Conic Section Graph Analysis
You can determine approximations of the following analytical results using conic section
graphs.
• Focus/vertex/eccentricity
• Length of latus rectum
• Center/radius
•
x
-/
y
-intercept
• Directrix/axis of symmetry drawing and analysis
• Asymptote drawing and analysis
1. From the Main Menu, enter the CONICS mode.
2. Use
f and c to select the conic section you want to analyze.
3. Input the conic section constants.
4. Draw the Graph.
After graphing a conic section, press !5(G-SLV) to display the following graph analysis
menus.
u Parabolic Graph Analysis
• {FOCS}/{VTX}/{LEN}/{e} ... {focus}/{vertex}/{length of latus rectum}/{eccentricity}
• {DIR}/{SYM} ... {directrix}/{axis of symmetry}
• {X-IN}/{Y-IN} ... {
x
-intercept}/{
y
-intercept}
u Circular Graph Analysis
• {CNTR}/{RADS} ... {center}/{radius}
• {X-IN}/{Y-IN} ... {
x
-intercept}/{
y
-intercept}
u Elliptical Graph Analysis
• {FOCS}/{VTX}/{CNTR}/{e} ... {focus}/{vertex}/{center}/{eccentricity}
• {X-IN}/{Y-IN} ... {
x
-intercept}/{
y
-intercept}
u Hyperbolic Graph Analysis
• {FOCS}/{VTX}/{CNTR}/{e} ... {focus}/{vertex}/{center}/{eccentricity}
• {ASYM} ... {asymptote}
• {X-IN}/{Y-IN} ... {
x
-intercept}/{
y
-intercept}
The following examples show how to use the above menus with various types of conic
section graphs.
