Problem 6E

Prove the identity laws in Table 1 by showing that

a) A ∪ ∅ = A.

b) A ∩ U = A.

 

Step-by-Step Solution:
Step 1 of 3

Step-1:

   

 NOTE: A set A is a subset of a set B  , or equivalently  B is  a superset of A , if A is contained inside B, that is all elements of A are also elements of B. A and B may coincide.That is

                                               

    UNION: The union of  two  sets  A and B  is  the  set containing  all elements that are in A  or in B ( possibly both).

       Then it is denoted by    , we can write  if and only if  or .

       Note :

     Example :

          A= { a, b} , B = {b ,c} then .

   The union of sets A and B is  shown by the shaded area in the venn diagram:

                                       

                 

Step-2:                                       

  a)In this problem we need to show that .

     Consider ,  .

      By the definition of union   (or)  .

      We know that   is a null set .So ,   .

      Therefore ,  ...
