    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

    and

    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!

    Well, suppose you have \bigcup_{j=1}^kA_j. How do you turn in into \bigcup_{j=1}^{k+1}A_j?
