P. 7
Operation on sets
Example1:
If X = { 3 , 4 } , Y = { 4 , 5 } , and Z = { 6 , 5 } find :
a) ?? × ( ?? n ?? ) = { 3 , 4 } × { 5 }
={(3,5),(4,5)}
a) ( ?? - ??) × ( ?? - ??) = { 3 } × { 4 } = { ( 3 , 4 ) }
b) ( ?? - ??) × ?? = { 3 } × { 4 , 5 } = { ( 3 , 4 ) , ( 3 , 5 ) }
Example2:
If X = { 3 , 4 } , Y = { 4 , 5 } , and Z = { 6 , 5 } find :
a) ( ?? - ??) × ( ?? ? ??) = { 6 } × { 3 , 4 , 5 } = { ( 6 , 3 ) , ( 6 , 4 ) , ( 6 , 5 ) }
Example3:
If X = { 1 , 3 , 5 } , Y = { 4 , 5 } , find ( ?? n ??) × ( ?? ? ??)
{ 4 } × { 1 , 3 , 4 , 5 } = { ( 4 , 1 ) , ( 4 , 3 ) , ( 4 ,4 ) , ( 4 , 5 ) }
