Set Recursive Definitions

Please help me with the following question about unions and intersections:

Given sets A1,A2,A3,...., develop recursive definitions for

U from j=1 to k of Aj


Intersection from j=1 to k of Aj

Need to find and prove an extension of De Morgan's laws for these unions and intersections. Thank you in advance for the help!

Re: Set Recursive Definitions

How do you add numbers a+b+c+d+...+k ?

Can you do the same thing with the union of sets?
