Ellipse, Hyperbola, and Sequence Flashcards
(75 cards)
elongated
sphere similar
to the shape of
the orbit of the
Earth in the
solar system.
Ellipse
eccentricity is
0 < e < 1
Ellipse
formed by a locus of points
whose sum of the distance from the two fixed points is constant (2a).
Ellipse
has closed and symmetrical figure.
Ellipse
two sets of foci, directrices, latera
recta and symmetrical axes.
Ellipse
two vertices and two co-vertices.
Ellipse
sum of the distances is constant and equal to the length of the major axis.
Ellipse
midpoint inside of the
ellipse curve
CENTER
detonated by the symbol C.
CENTER
main points of the curve
VERTICES
expressed by the symbols V
VERTICES
fixed points of the Ellipse
FOCI
plural form of Focus
FOCI
located between the center and the vertices
FOCI
represented by the symbol F1 and F2
FOCI
the lines which are located outside
of the ellipse
DIRECTRIX LINE
divides the curve into two
symmetrical parts.
MINOR AXIS
The end points of this
axis are called intercepts.
MINOR AXIS
The length is 2b
MINOR AXIS
MAJOR AXIS also known as
PRINCIPAL AXIS
symmetrical axis in the ellipse but always longer in length compare to minor axis.
PRINCIPAL AXIS /MAJOR AXIS
endpoints are the vertices.
PRINCIPAL AXIS /MAJOR AXIS
length of this axis is 2a
PRINCIPAL AXIS /MAJOR AXIS
distance between
the one of the focus to the Center.
FOCAL DISTANCE
