Union Command
From GeoGebra Manual
- Union[ <List 1>, <List 2> ]
- 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 poly1>, <Polygon poly2> ]
- 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.
