Conic Section 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 + (Y – K) 2 = R 2
A = 0 for AX 2 + AY 2 + BX + CY + D = 0
(3) Ellipse/hyperbola graph
A = 0 or B = 0
