• Conic section graphs can be drawn in blue only.

CFX

• You cannot overwrite conic section graphs.

• The calculator automatically clears the screen before drawing a new conic

section graph.

• You can use trace, scroll, zoom, or sketch after graphing a conic section.

However, a conic section graph cannot be scrolled while using trace.

• You cannot incorporate graphing of a conic section into a program.

• A parabola is the locus of points equidistant from fixed line

not on the line. Fixed point F is the "focus," fixed line

horizontal line that passes through the focus directrix is the "axis of symme-

try," the length of a straight line that intersects the parabola, passes through

the locus, and is parallel to fixed line

the parabola intersects the axis of symmetry is the "vertex."

Axis of symmetry

• An ellipse is the locus of points the sum of the distances of each of which

from two fixed points F and F' is constant. Points F and F' are the "foci,"

points A, A', B, and B' where the ellipse intersects the x- and y-axes are the

"vertexes," the x-coordinate values of vertexes A and A' are called

x-intercepts, and the y-coordinate values of vertexes B and B' are called

y-intercepts.
