A coordinate system used to specify
locations in space consists of:
A fixed reference point
O
, called the origin.
A set of specified axes with appropriate scales
and labels on the axes.
Instructions that tell us how to label a point in
space relative to the origin and axes.
1.1 Coordinate Systems
A common coordinate system is called the
Cartesian
Coordinate system, Sometimes
called the Rectangular
Coordinate system,
This system labeled with the coordinate
(X,Y).
The Cartesian Coordinate can be expressed
through equations relating the coordinates
(X,Y) to the Plane polar coordinates system
(r,
). As follows:
