UNIT 9  : THE CONICS

LESSON 1: DEFINITION OF LOCUS

 

The Concept of Locus:

Locus is derived from the Latin word for place or position.

 

Definition:   A locus of points is a set of points which satisfy one or more given conditions.

 

A simple example is a circle.  A circle is a locus (set) of points each of which is a constant distance

from a fixed point.  The fixed point is the centre of the circle and the fixed distance is the radius.
