The origin of a coordinate system is the center point or zero point where the axes meet.
Euclidean
In the Euclidean plane 
, the origin is 
. Similarly, in the Euclidean space 
, the origin is 
. This way, in general, the origin of an 
-dimensional Euclidean space 
is the -tuple 
with all its components equal to zero.
Thus, the origin of any coordinate system is the point where all of its components are equal to zero.
