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} ... {

u Circular Graph Analysis

• {CNTR}/{RADS} ... {center}/{radius}

• {X-IN}/{Y-IN} ... {

u Elliptical Graph Analysis

• {FOCS}/{VTX}/{CNTR}/{e} ... {focus}/{vertex}/{center}/{eccentricity}

• {X-IN}/{Y-IN} ... {

u Hyperbolic Graph Analysis

• {FOCS}/{VTX}/{CNTR}/{e} ... {focus}/{vertex}/{center}/{eccentricity}

• {ASYM} ... {asymptote}

• {X-IN}/{Y-IN} ... {

y

-intercept}

The following examples show how to use the above menus with various types of conic
section graphs.
