Vertex[ <Conic> ]
Returns (all) vertices of the conic section.
Vertex[ <Inequality> ]
Returns the points of intersection of the borders.
Example:
  • Vertex[(x + y < 3) && (x - y > 1)] returns point A = (2, 1).
  • {Vertex[(x + y < 3) ∧ (x - y > 1) && (y > - 2)]} returns list1 = {(2, 1), (5, -2), (-1, -2)}.
  • Vertex[(y > x²) ∧ (y < x)] returns two points A = (0, 0) and B = (1, 1).
  • {Vertex[(y > x²) ∧ (y < x)]} returns list1 = {(0, 0), (1, 1)}.
Vertex[ <Polygon> ]
Returns (all) vertices of the polygon.
Vertex[ <Polygon>, <Index> ]
Returns n-th vertex of the polygon.
Note: To get the vertices of the objects polygon / conic / inequality in a list, use {Vertex[Object]}.
