5-11-17 Function Analysis 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. 20050401
