Union Command
From GeoGebra Manual
- Union[ <List>, <List> ]
- Joins the two lists and removes elements that appear multiple times.
- Example:
Union[ {1, 2, 3, 4, 5}, {3, 2, 1, 7} ]yields{1, 2, 3, 4, 5, 7}.
- Union[ <Polygon>, <Polygon> ]
- Finds the union of the two polygons. Works only for where the polygons are not self-intersecting, and where the union is a single polygon.
