Study Notes

Venn Diagrams

A Venn diagram is a pictorial representation of sets, where an enclosed area in the plane represents sets.

Set Operations

Union of Sets: The union of sets A and B (A∪B) is the set of all elements that belong to A or B or both.
Intersection of Sets: The intersection of sets A and B (A ∩ B) is the set of all elements that belong to both A and B.
Difference of Sets: The difference of sets A and B (A - B) is the set of all elements that belong to A but not to B.
Complement of a Set: The complement of set A (Ac) is the set of all elements of the universal set that do not belong to A.
Symmetric Difference of Sets: The symmetric difference of sets A and B (A ⨁ B) is the set of all elements that are in A or B but not in both.

Functions

An identity function is a function f where each element of set A has an image on itself.
