This document defines key terms related to hyperbolas and provides examples of finding the standard form of the equation of a hyperbola given certain properties. It defines a hyperbola as a set of points where the absolute difference between the distances to two fixed points (foci) is a constant. It provides examples of identifying the vertices, foci, asymptotes, and standard form of the equation from information given, such as the coordinates of vertices and foci or the asymptotes.

2. •Define a hyperbola.
•Determine the standard
form of equation of a
hyperbola.

3. • State the definition of
hyperbola.
• Recognize the parts of the
hyperbola given their
corresponding description.

4. • Identify the value of the parts of
the hyperbola given its equation
in standard form.
• Find the equation of the
hyperbola in standard form
determined by the given
conditions.

6. The difference of the distances
between the foci and a point
on the hyperbola is fixed.

7. The set of all points such that the
absolute value of the difference of
the distance of each point from
two fixed points is a constant.

9. The line passing through
the two foci intersects the
hyperbola at its vertices.
The line segment that is
perpendicular to the
conjugate axis and
contains the vertices is
called the transverse
axis.
Midpoint of the transverse
axis is called the center of
the hyperbola
The line segment perpendicular to the
transverse axis and passing through the
center is the conjugate axis.
Asymptotes are straight lines that
contain the diagonals of a rectangle
drawn at the center of the hyperbola
The distance between the vertex and the center is a, while the
distance between the focus and the center is c. We get the
value of c using the relationship c2=a2+b2

20. Find the standard form of the
equation of the hyperbola
with center at the origin, foci
(±7,0) , and vertices (±5,0).

21. Determine the value of
a.
Since a is the distance between the
center (0,0) and the vertex (5,0),
a=5
Furthermore, since the vertices lie
on the x-axis, the hyperbola has a
horizontal transverse axis.

22. Determine the value
of c.
Since c is the distance between
the center (0,0) and the focus (7,0),
c=7

Thus, the center of the hyperbola
is (0,0)

29. Determine the value
of a.
Since a is the distance from the
center to the vertex, then a=10.
Furthermore, since the vertices
lie on the y-axis, the hyperbola has a
vertical transverse axis.

30. Determine the slopes
of the asymptotes.
Since the hyperbola has a vertical
transverse axis, asymptotes are of
the form y=±

x. thus, y= ±5x.
Therefore the slopes are m1= 5
and m2= ‒5.

Thus, b=
