k Implicit Function Graph Analysis
You can determine approximations of the following analytical results using implicit function
graphs.
•Focus/vertex/eccentricity
• Latus rectum
• Center/radius
• x-/y-intercept
•Directrix/axis of symmetry drawing and analysis
•Asymptote drawing and analysis
After graphing an implicit function, press 4(G-SLV) to display the following graph analysis
menus.
u Parabolic Graph Analysis
• {Focus}/{Vertex}/{Length}/{e} ... {focus}/{vertex}/{lactus rectum}/{eccentricity}
• {Dirtrx}/{Sym} ... {directrix}/{axis of symmetry}
• {X-Icpt}/{Y-Icpt} ... {x-intercept}/{y-intercept}
u Circular Graph Analysis
• {Center}/{Radius} ... {center}/{radius}
• {X-Icpt}/{Y-Icpt} ... {x-intercept}/{y-intercept}
u Elliptical Graph Analysis
• {Focus}/{Vertex}/{Center}/{e} ... {focus}/{vertex}/{center}/{eccentricity}
• {X-Icpt}/{Y-Icpt} ... {x-intercept}/{y-intercept}
u Hyperbolic Graph Analysis
• {Focus}/{Vertex}/{Center}/{e} ... {focus}/{vertex}/{center}/{eccentricity}
• {Asympt} ... {asymptote}
• {X-Icpt}/{Y-Icpt} ... {x-intercept}/{y-intercept}
The following examples show how to use the above menus with various types of implicit
function graphs.
