Definition of «locus»

Locus is a Latin term that refers to a place, position or location. In mathematics, specifically in geometry and algebra, locus has a more specific definition as the set of all points that satisfy certain conditions. For example, if you draw a curve on a graph with a pencil, the path traced by the point of contact between the pencil and the paper is called the locus of the pencil point. In algebra, the locus of a variable can be determined using equations or inequalities that describe its possible values within a given context.
