A circle is the set of points in a plane whose distance
from a given fixed point in the plane is constant. The
fixed point is the centre of the circle; the constant
distance is the radius.

Ellipse

An ellipse is the set of points whose distances from two
fixed points in the plane have a constant sum. The two
fixed points are the foci of the ellipse. The line through
the foci of an ellipse is the ellipse's focal axis. The point
on the axis halfway between the foci is the centre. The
points where the focal axis and ellipse intersect are the
ellipse's vertices.

Hyperbola

A hyperbola is the set of points in a plane whose
distances from two fixed points in the plane have a
constant difference. The two fixed points are the foci of

the hyperbola. The line through the foci of the hyperbola
is the focal axis. The point on the axis halfway between
the foci is the hyperbola's centre. The points where the
focal axis and hyperbola cross are the vertices.
Parabola

A set that consists of all the points in a plane equidistant
from a given fixed point and a given fixed line in the
plane is a parabola. The fixed point is the focus of the
parabola. The fixed line is the directrix. The point where
the focal axis intersects the parabola is the vertex.

Example Activity – Polynomial Root Finder
Use this activity to learn the basics of the App.

A golfer hits a golf ball from a tee at the bottom of a hill.
You can describe the hill by y(x) =0.8x.
The ball follows the path y(x) = -x2 + 12x.
If the golfer is standing at the tee (0, 0) and hits the ball, where does the ball hit the
ground on the hill?
First, equate the two equations:
x2 + 12x = 0.8x
-x2 + 11.2x = 0
The roots of the resulting polynomial will give the intersection points of the ball path
and the hill.
