The document defines and explains hyperbolas through the following key points:
1. A hyperbola is the set of points where the absolute difference between the distance to two fixed points (foci) is a constant.
2. Key parts of a hyperbola include vertices, foci, transverse axis, and conjugate axis.
3. The standard equation of a hyperbola is (x2/a2) - (y2/b2) = 1
4. Examples are worked through to graph specific hyperbolas using their equations.
1. 10.3 Hyperbolas
John 17:3 "And this is eternal life, that they know you the
only true God, and Jesus Christ whom you have sent."
2. Another way to define
the hyperbola is this:
A Hyperbola is the set
of points in the plane,
the difference of whose
distances from two
fixed points (the Foci),
is a constant.

11. To derive the equation for a hyperbola ... start with
PF2 − PF1 = 2a
12. To derive the equation for a hyperbola ... start with
PF2 − PF1 = 2a
It is very similar to what we did with the ellipse, so we
won’t go through all of that again. The equation is:
