Implicit Function Graph Analysis
You can determine approximations of the following analytical results using implicit
function graphs.
• Focus/vertex calculation
• Latus rectum calculation
• Center/radius calculation
•
x
-/
y
-intercept calculation
• Directrix/axis of symmetry drawing and analysis
• Asymptote drawing and analysis
After graphing an implicit function, press
5
(G-Solv) to display the Graph Analysis
Menu.
• Parabolic Graph Analysis
1
(FOCS) .... Determines the focus.
2
(SYM) ....... Draws the axis of symmetry.
3
(DIR) ........ Draws the directrix.
4
(VTX) ....... Determines the vertex.
5
(LEN) ....... Determines the latus rectum.
• Circle Graph Analysis
1
(CNTR) .... Determines the center.
2
(RADS) .... Determines the radius.
• Ellipse Graph Analysis
1
(FOCS) .... Determines the focus.
2
(X-IN) ....... Determines the
x
-intercept.
3
(Y-IN) ........ Determines the
y
-intercept.
• Hyperbolic Graph Analysis
1
(FOCS) .... Determines the focus.
2
(X-IN) ....... Determines the
x
-intercept.
3
(Y-IN) ........ Determines the
y
-intercept.
4
(VTX) ....... Determines the vertex.
5
(ASYM) .... Determines the asymptote.
The following examples show how to use the above menus with various types of
