  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.
