Implicit Function Graphing Precautions - Casio fx9750G User Manual

14-4 Implicit Function Graphing Precautions

• Assigning the following types of values to variables contained in built-in function
produces an error.
(1) Parabola graph
A = 0
(2) Circle graph
R = 0 for (X – H)
2
A = 0 for AX
(3) Ellipse/hyperbola graph
A = 0 or B = 0
• You cannot overwrite implicit function graphs.
• The calculator automatically clears the screen before drawing a new implicit func-
tion graph.
• You can use trace, scroll, zoom, or sketch after graphing an implicit function.
However, an implicit function graph cannot be scrolled while using trace.
• You cannot incorporate graphing of an implicit function into a program.
