Question
Express the truth of each of the following statements using Venn diagrams:
(a) No circles are polygons
(b) Some quadratic equations have equal roots
Solution
(a) Let u: The set of closed geometrical figures in the plane.
Let A: The set of all polygons and
B: The set of all circles
Hence the following is the Venn diagram.
(b) Let u: The set of all equations.
Let A: The set of all quadratic equations and
B: The set of all quadratic, equations having equal roots.
Hence the following is the Venn d6agram.
